Crystal structure of di-chlorido-(1,2-phenyl-enedi-amine-?²N,N')platinum(II).

ABSTRACT: The Pt^II atom in the title compound, [PtCl₂{(C₆H₄)(NH₂)₂}], lies on a twofold rotation axis and has a slightly distorted square-planar coordination environment defined by two N atoms of an 1,2-phenyl-enedi-amine ligand and two Cl^- ions. In the crystal, the planar complex mol-ecules are stacked parallel to the c axis, resulting in a columnar structure. In a column, an infinite almost straight Pt?Pt chain is formed, suggesting weak metal-metal inter-actions [Pt?Pt = 3.3475?(8)?Å]. The crystal packing is stabilized by a three-dimensional N-H?Cl hydrogen-bonding network between the amino groups and the Cl ligands of adjacent mol-ecules.

Crystal structure of cis-[1,2-bis-(di-phenyl-phosphan-yl)ethene-?2P,P']di-chlorido-platinum(II) chloro-form disolvate: a new polymorph.

Project description:The title compound, [PtCl2(C26H22P2)]·2CHCl3 (I), is the third monoclinic polymorph of this platinum(II) complex involving the bidentate ligand cis-1,2-bis-(di-phenyl-phosphan-yl)ethyl-ene (cis-dppe) [for the others, see: Oberhauser et al. (1998a ?). Inorg. Chim. Acta, 274, 143-154, and Oberhauser et al. (1995 ?). Inorg. Chim. Acta, 238, 35-43]. The structure of compound (I) was solved in the space group P21/c, with one complex mol-ecule in the asymmetric unit along with two solvate chloro-form mol-ecules. The PtII atom is ligated by two P and two Cl atoms in the equatorial plane and has a perfect square-planar coordination sphere. In the crystal, the complex mol-ecule is linked to the chloro-form solvate mol-ecules by C-H?Cl hydrogen bonds and face-on C-Cl?? inter-actions. There are also weak offset ?-? inter-actions present [inter-centroid distances are 3.770?(6) and 4.096?(6)?Å], linking the mol-ecules to form supra-molecular sheets that lie in the bc plane.

Crystal structures of di-chlorido-palladium(II), -platinum(II) and -rhodium(III) complexes containing 8-(di-phenyl-phosphan-yl)quinoline.

Project description:The crystal structures of di-chlorido-palladium(II), -platinum(II) and -rhodium(III) complexes containing 8-(di-phenyl-phosphan-yl)quinoline, (SP-4)-[PdCl2(C21H16NP)], (1) [systematic name: di-chlor-ido-(8-di-phenyl-phosphanyl-quinoline)-palladium(II)], (SP-4)-[PtCl2(C21H16NP)]·CH2Cl2, (2) [systematic name: di-chlorido-(8-di-phenyl-phos-phanyl-quinoline)-platinum(II) dichlorometh-ane monosolvate], and (OC-6-32)-[RhCl2(C21H16NP)2]PF6·0.5CH2Cl2·0.5CH3OH, (3) [systematic name: cis-di-chlor-ido-bis-(8-di-phenyl-phosphanyl-quinoline)-rhodium(III) hexa-fluorido-phos-phate di-chloro-methane/-methanol hemisolvate] are reported. In these complexes, the phosphanyl-quinoline acts as a bidentate ligand, forming a planar asymmetrical five-membered chelate ring. The palladium(II) and platinum(II) complex mol-ecules in (1) and (2), respectively, show a typical square-planar coordination geometry and form a dimeric structure through an inter-molecular ?-? stacking inter-action between the quinolyl rings. The centroid-centroid distances between the stacked six-membered rings in (1) and (2) are 3.633?(2) and 3.644?(2)?Å, respectively. The cationic rhodium(III) complex in (3) has a cis(Cl),cis(P),cis(N) (OC-6-32) configuration of the ligands, in which two kinds of intra-molecular ?-? stacking inter-actions are observed: between the quinolyl and phenyl rings and between two phenyl rings, the centroid-centroid distances being 3.458?(2) and 3.717?(2)?Å, respectively. The PF6 (-) anion in (3) is rotationally disordered, the site occupancies of each F atom being 0.613?(14) and 0.387?(14). The CH2Cl2 and CH3OH solvent mol-ecules are also disordered and equal site occupancies of 0.5 are assumed.

Crystal structure of [N,N'-bis-(4-methyl-phen-yl)-1,2-di-phenyl-ethane-1,2-di-imine-κ(2) N,N']di-chlorido-palladium(II) methanol monosolvate.

Project description:The title compound, [PdCl2(C28H24N2)]·CH3OH, was pre-pared from the reaction of PdCl2(DMSO)2 (DMSO is di-methyl sulfoxide) and N,N'-bis-(4-methyl-phen-yl)-1,2-di-phenyl-ethane-1,2-di-imine in methanol. The chelating di-imine core of the title compound deviates slightly from planarity, with an N-C-C-N torsion angle of 5.3 (3)°. Delocalization in the di-imine core is indicated by N-C and C-C bonds that are, respectively, longer and shorter than those found in related nonchelating di-imines. The distorted square-planar coordination environment around the Pd(II) atom is manifested as bond angles that are smaller and larger than 90°, and palladacycle torsion angles of -173.22 (16) and 167.06 (16)°. These deviations are attributed to the small bite angle of 79.13 (8)° of the di-imine chelate. The crystal packing exhibits weak inter-molecular hydrogen-bonding inter-actions involving aromatic H atoms, Cl atoms and inter-calated methanol solvent mol-ecules, defining layers parallel to (010).

Crystal structure of di-μ-chlorido-bis(chlorido-{N (1)-phenyl-N (4)-[(pyridin-2-yl-κN)methyl-idene]benzene-1,4-di-amine-κN (4)}mercury(II)).

Project description:The whole mol-ecule of the title complex, [Hg2Cl4(C18H15N3)2], is generated by inversion symmetry. It was synthesized from the pyridine-derived Schiff base N-phenyl-N'-[(pyridin-2-yl)methyl-idene]benzene-1,4-di-amine (PPMBD). The five-coordinated Hg(2+) ions have a distorted square-pyramidal environment defined by two N atoms, viz. the imine and the other pyridyl [Hg-N = 2.467 (6) and 2.310 (6) Å, respectively] belonging to the bidentate imino-pyridine ligand, and three Cl atoms [Hg-Cl = 2.407 (2), 2.447 (2) and 3.031 (2) Å]. The longest Hg-Cl bond is bridging about the inversion centre. In the ligand, the central ring and pyridine ring are oriented at a dihedral angle of 8.1 (4)°, while the planes of the pyridine ring and the terminal phenyl ring are oriented at a dihedral angle of 53.8 (4)°. In the crystal, mol-ecules are linked by N-H⋯Cl and C-H⋯Cl hydrogen bonds, forming sheets parallel to (001).

Redetermination of the crystal structure of catena-poly[[[bis-(ethyl-enedi-amine)-platinum(II)]-μ-iodido-[bis-(ethyl-enedi-amine)-platinum(IV)]-μ-iodido] tetra-kis-(octane-1-sulfonate) dihydrate].

Project description:The structure of the title compound, which represents a mixed-valence platinum(II,IV) complex, {[Pt(II)Pt(IV)I2(C2H8N2)4][CH3(CH2)7SO3]4·2H2O} n , has been redetermined in a different space group. In contrast to the previously reported determination in the space group P21 cn [Matsushita & Taira (1999 ▸). Synth. Met. 102, 1787-1788], the current model was refined in the centrosymmetric space group Pmcn using the original diffraction data. The title compound has a linear chain structure composed of square-planar [Pt(en)2](2+) and elongated octa-hedral trans-[PtI2(en)2](2+) cations (en is ethyl-enedi-amine) stacked alternately, bridged by the I atoms, parallel to the c axis. Inorganic layers aligned parallel to the bc plane, composed of the Pt-complex columns, the -SO3 (-) part of the octane-1-sulfonate anion, and the water mol-ecule of crystallization, are stacked alternately with organic layers composed of the long-chain alkyl groups along the a axis. The Pt and I sites are located on the same mirror plane whereby the I site is equally disordered over two positions. The Pt and I atoms form a slight zigzag ⋯I-Pt(IV)-I⋯Pt(II)⋯ chain, with Pt(IV)-I bond lengths of 2.6888 (17) and 2.7239 (17) Å, Pt(II)⋯I contacts of 3.2065 (17) and 3.1732 (16) Å, and Pt(IV)-I⋯Pt(II) angles of 178.3 (3) and 176.7 (2)°. The mixed-valence state of the Pt site is expressed by the structural parameter δ = (Pt(IV)-I)/(Pt(II)⋯I), with values of 0.839 and 0.858 for the two independent I atoms. In the crystal, N-H⋯O hydrogen bonds involving the cationic chains, the sulfonate groups and water mol-ecules of crystallization, stabilize the columnar structure.

Di-?-chlorido-bis-[chlorido(dimethoxy-phenyl-phosphine)palladium(II)].

Project description:The title compound, [Pd(2)Cl(4)(C(8)H(11)O(2)P)(2)], is binuclear and disposed about a crystallographic centre of symmetry with a Pd?Pd distance of 3.4662?(17)?Å. It has a similar geometry to that observed in the triphenyl-phosphite and triphenyl-phosphine analogues. The Pd-P bond length is ca 0.04?Å shorter than those in mononuclear PdCl(2)(P(OMe)(2)Ph)(2), possibly due to the lower trans-influence of the bridging Cl(-) compared to a single-bonded Cl(-) atom.

Crystal structure of {bis-[2-(3,5-di-methyl-pyrazol-1-yl-κN (2))eth-yl]amine-κN}chlorido-platinum(II) chloride dihydrate.

Project description:The title complex, [PtCl(C14H23N5)]Cl·2H2O, is isomorphous with the Pd(II) compound characterized previously [Mendoza, Bernès & Mendoza-Díaz (2006 ▶). Acta Cryst. E62, m2934-m2936]. The angle between pyrazole mean planes in the main ligand is 88.3 (4)°, similar to that observed in the Pd(II) analogue [87.62 (11)°]. This tridentate ligand adopts a conformation approximating a twofold symmetry, allowing its coordination to the metal atom, together with a chloride ligand, in an almost perfect square-planar geometry. A chloride anion and two water mol-ecules in the asymmetric unit form a hydrogen-bonded network connected to the complex mol-ecules in the crystal via the NH amine groups, forming chains along [100].

Crystal structures of (Z)-(ethene-1,2-di-yl)bis-(di-phenyl-phosphine sulfide) and its complex with PtII dichloride.

Project description:The crystal structures of (Z)-(ethene-1,2-di-yl)bis-(di-phenyl-phosphine sulfide), C26H22P2S2 (I), along with its complex with PtII dichloride, di-chlorido[(Z)-(ethene-1,2-di-yl)bis-(di-phenyl-phosphine sulfide)-κ2 S,S']platinum(II), [PtCl2(C26H22P2S2)] (II), are described here. Compound I features P=S bond lengths of 1.9571 (15) and 1.9529 (15) Å, with a torsion angle of 166.24 (7)° between the two phosphine sulfide groups. The crystal of compound I features both intra-molecular C-H⋯S hydrogen bonds and π-π inter-actions. Mol-ecules of compound I are held together with inter-molecular π-π and C-H⋯π inter-actions to form chains that run parallel to the z-axis. The inter-molecular C-H⋯π inter-action has a H⋯Cg distance of 2.63 Å, a D⋯Cg distance of 3.573 (5) Å and a D-H⋯Cg angle of 171° (where Cg refers to the centroid of one of the phenyl rings). These chains are linked by relatively long C-H⋯S hydrogen bonds with D⋯A distances of 3.367 (4) and 3.394 (4) Å with D-H⋯A angles of 113 and 115°. Compound II features Pt-Cl and Pt-S bond lengths of 2.3226 (19) and 2.2712 (19) Å, with a P=S bond length of 2.012 (3) Å. The PtII center adopts a square-planar geometry, with Cl-Pt-Cl and S-Pt-S bond angles of 90.34 (10) and 97.19 (10)°, respectively. Mol-ecules of compound II are linked in the crystal by inter-molecular C-H⋯Cl and C-H⋯S hydrogen bonds.

Crystal structure of 5-chloro-N1-(5-phenyl-1H-pyrazol-3-yl)benzene-1,2-di-amine.

Project description:The title compound, C15H13ClN4, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit, which are far from planar as a result of steric repulsion between the rings. The benzene and phenyl rings are inclined to the central pyrazole ring by 46.64 (10) and 17.87 (10)° in mol-ecule A, and by 40.02 (10) and 14.18 (10)° in mol-ecule B. The aromatic rings are inclined to one another by 58.77 (9)° in mol-ecule A, and 36.95 (8)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked by two pairs of N-H⋯N hydrogen bonds forming A-B dimers. These are further linked by a fifth N-H⋯N hydrogen bond, forming tetra-mer-like units that stack along the a-axis direction, forming columns, which are in turn linked by C-H⋯π inter-actions, forming layers parallel to the ac plane.
