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

ABSTRACT: 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.

cis-Dichloridobis(dimethoxy-phenyl-phosphine)palladium(II).

Project description:The title compound, [PdCl(2)(C(8)H(11)O(2)P)(2)], has a comparable structure to those of related palladium dichloride complexes containing trimethyl phosphinite and methyl diphenyl phosphinite. The Pd atom is located on a crystallographic twofold rotation axis: thus, there is just one half-mol-ecule in the asymmetric unit. The structure is isomorphous with the platinum analogue cis-[PtCl(2){P(OMe)(2)Ph}(2)].

Di-μ-chlorido-bis-{[2-(morpholinometh-yl)phenyl-κC,N]palladium(II)}.

Project description:The title compound, [Pd(2)(C(11)H(14)NO)(2)Cl(2)], has a dimeric structure with Cl atoms bridging the two Pd atoms, one half of the mol-ecule being generated by symmetry due to the crystallographic inversion centre located in the middle of the perfectly planar Pd(2)Cl(2) ring. The five-membered ring adopts an envelope conformation, while the morpholino group has a chair conformation. The geometry around the metal centres is distorted square-planar, as a result of a strong intra-molecular N→Pd coordination trans to a Pd-Cl bond. In the crystal structure, the dimeric structure is strengthened by inter-molecular C-H⋯Cl hydrogen bonds. C-H⋯C(phen-yl) inter-actions link the dimers into a columnar supra-molecular array along the a axis; the dimers are further connected by C-H⋯Ph inter-actions into a three-dimensional supra-molecular arrangement.

trans-Di-chlorido-bis-(pyridazine-?N)palladium(II).

Project description:The title compound, [PdCl2(C4H4N2)2], contains two crystallographically unique complexes; the Pd(II) atom lies on an inversion center in both cases. The two pyridazine units bonded to the Pd(II) atom are thus coplanar although dihedral angles within each complex are different. In one complex, the angle between the ring plane and Pd-Cl bond is almost perpendicular [89.4?(1)°], while the other is tilted with an angle of 60.0?(1)°. In the crystal, weak C?H-N hydrogen bonds and C?H-Cl inter-actions connect the two independent complex mol-ecules.

Bis[2-phenyl-1-(phenyl-iminio)isoindo-line] di-?-chlorido-bis-[dichloridopalladate(II)] benzene disolvate.

Project description:In the title compound, (C(20)H(17)N(2))(2)[Pd(2)Cl(6)]·2C(6)H(6), the dichloride-bridged [Pd(2)Cl(6)](2-) anion lies across an inversion center with each Pd(II) ion in a slightly distorted square-planar environment. In the crystal structure, two cations and an anion are connected via N-H?Cl hydrogen bonds between the NH groups of the iminioisoindoline cations and terminal Cl atoms of a hexa-chloridodipalladate(II) anion. The Pd-Cl distance of the terminal chloride engaged in hydrogen bonding is slightly longer than the Pd-Cl distance of the adjacent terminal chloride which is not involved in hydrogen bonding.

Di-?-chlorido-bis-{chlorido[(R)/(S)-1,5-di-phenyl-3-(2-pyridyl-?N)-2-pyrazoline-?N]zinc(II)}.

Project description:In the centrosymmetric binuclear title compound, [Zn(2)Cl(4)(C(20)H(17)N(3))(2)], the coordination geometry of the Zn(II) ion can be described as a distorted ZnN(2)Cl(3) trigonal bipyramid (? = 0.89), arising from the N,N'-bidentate ligand, a terminal chloride ion and two bridging chloride ions. The N atoms occupy one axial and one equatorial site and the terminal chloride ion occupies an equatorial site. The dihedral angle between the pyridine and pyrazole rings is 12.8?(2)°. In the crystal, aromatic ?-? stacking [centroid-centroid separations = 3.812?(3) and 3.848?(3)?Å] and C-H?Cl and C-H?? inter-actions help to establish the packing.

Di-?-chlorido-bis-{[4-chloro-2-(dimethyl-amino-meth-yl)phenyl-?C,N]palladium(II)}.

Project description:The title compound, [Pd(2)(C(9)H(11)ClN)(2)Cl(2)], consists of two Pd atoms which are bridged by two Cl atoms, forming a centrosymmetric binuclear complex with a square-planar coordination for each of the Pd atoms. The Pd atom is chelated by one N and one C atom from a 4-chloro-2-(dimethyl-amino-meth-yl)phenyl ligand, forming a five-membered ring (N-Pd-C-C-C). In the crystal structure, weak C-H ?Cl hydrogen bonds link the mol-ecules in rows.

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 bis-{?-2-[(di-methyl-amino)-meth-yl]ferrocene-seleno-lato}bis[chlorido-palladium(II)].

Project description:The dinuclear title compound, [PdCl{Se[(C5H5)Fe(C5H3)2CH2N(CH3)2]}]2 was obtained by the reaction of [PdCl2(NCPh)2] with 2-[(N,N'-di-methyl-amino)-meth-yl]ferro-cene-seleno-late and the crystals for the structure determination were grown from a mixture of THF and n-hexane. Both Pd(II) atoms are coordinated by the bridging Se atoms and by the amino N atoms of the bidentate 2-[(N,N'-di-methyl-amino)-meth-yl]ferrocene-seleno-late ligand, as well as by Cl atoms, and show a distorted square-planar coordination. The angle between the Pd-Se-Se planes of the two Pd atoms is 149.31?(3)°. Weak Cl?H hydrogen bonds link the binuclear complexes into a three-dimensional network.

Di-?-chlorido-dichlorido-bis{?-6,6'-dimethoxy-2,2'-[o-phenylenebis(nitrilomethylidyne)]diphenolato}dilead(II)dizinc(II) N,N'-dimethyl-formamide disolvate.

Project description:The title compound, [Pb(2)Zn(2)(C(22)H(18)N(2)O(4))(2)Cl(4)]·2C(3)H(7)NO, was synthesized using a step-by-step method and has a slipped sandwich configuration. The coordination environment of the Zn(2+) ion is distorted square-pyramidal and it is coordinated by N(2)O(2) of the Schiff base ligand and chloride; each Pb(2+) ion is coordinated by the four 6,6'-dimeth-oxy-2,2'-[o-phenyl-ene-bis(nitrilo-methyl-idyne)]diphenolate (L) O atoms and two chloride ions. The Zn(II)Pb(II) dinuclear unit, through an inversion-symmetry operation, forms a tetra-meric complex with double chloride bridges.
