Chlorido(2-formyl-6-hydroxy-phenyl-?C)mercury(II).

ABSTRACT: In the planar [r.m.s. deviation 0.0265?Å] title compound, [Hg(C(7)H(5)O(2))Cl], the Hg(II) atom shows a typical linear coordination by a C atom of a benzene ring and a Cl atom. The benzene C atom and the aldehyde O atom chelate the Hg(II) atom by assuming the Hg?O separation of 2.817?(9)?Å?as a weak intra-molecular coordination bonding distance. The resulting five-membered metallacycle is nearly coplanar with the benzene ring dihedral angle 2.9?(1)°]. Inter-molecular O-H?O hydrogen bonds are present in the crystal structure, resulting in a one-dimensional supra-molecular architecture parallel to [201].

Chlorido(5-formyl-2-hydroxy-phenyl-?C)mercury(II).

Project description:In the planar (r.m.s. deviation = 0.027?Å) title compound, [Hg(C(7)H(5)O(2))Cl], the Hg(II) atom shows a typical linear coordination by a C atom of the benzene ring and a Cl atom. Inter-molecular O-H?O hydrogen bonds are present in the crystal structure, resulting in chains propagating along the b axis. The crystal studied was a non-merohedral twin, with a twin ratio of 0.802?(2):0.198?(2).

catena-Poly[[chlorido(methyl phenyl sulfide-κS)mercury(II)]-μ-chlorido].

Project description:The title compound, [HgCl(2)(C(7)H(8)S)](n), was isolated from the reaction of MeSPh with HgCl(2). The Hg(II) atom has a distorted tetra-hedral geometry and is coordinated by one S atom and three Cl atoms. Two of the Cl atoms act as bridging ligands between the Hg atoms, forming a two-dimensional polymeric 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.

catena-Poly[[chloridomercury(II)]-μ-1,4-diaza-bicyclo-[2.2.2]octane-κN:N'-[chlorido-mercury(II)]-di-μ-chlorido].

Project description:In the title coordination polymer, [Hg(2)Cl(4)(C(6)H(12)N(2))](n), each Hg(II) center within the chain is four-coordinated by one terminal Cl atom, two bridging μ(2)-Cl atoms, and one N-atom donor from a μ(2)-1,4-diaza-bicyclo-[2.2.2]octane (μ(2)-daco) ligand in a distorted tetra-hedral geometry. The daco ligand acts as an end-to-end bridging ligand and bridges adjacent Hg(II) centers, forming a chain running along [001]. Weak C-H⋯Cl hydrogen-bonding inter-actions link the chains into a three-dimensional network. Comparison of the structural differences with previous findings suggests that the space between the two N donors, as well as the skeletal rigidity in N-heterocyclic linear ligands, may play an important role in the construction of such supra-molecular networks.

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).

Bis(tetra-phenyl-phospho-nium) tetra-chlorido-cobaltate(II).

Project description:The title compound, (C24H20P)2[CoCl4], was prepared under hydro-thermal conditions. In the crystal, the tetra-phenyl-phospho-nium cations are linked by pairs of weak C-H⋯π inter-actions into supra-molecular dimers; the Co(II) cations lie on twofold rotation axes and the tetra-hedral [CoCl4](2-) anions are linked with the tetra-phenyl-phospho-nium cations via weak C-H⋯Cl hydrogen bonds.

1-Phenyl-piperazine-1,4-diium tetra-chlorido-cobalt(II).

Project description:In the title mol-ecular salt, (C10H16N2)[CoCl4], the piperazine ring of the phenyl-piperazine dication adopts a chair conformation and the phenyl ring occupies an equatorial orientation. In the tetra-chlorido-cobaltate(II) dianion, the Co-Cl bond lengths for the chloride ions not accepting hydrogen bonds are significantly shorter than those for the chloride ions accepting such bonds. In the crystal, the components are linked by N-H⋯Cl hydrogen bonds, generating [001] chains.

Project description:In the mononuclear title complex, [HgCl2(C22H17N3)], synthesized from the quinoline-derived Schiff base N (1)-phenyl-N (4)-[(quinolin-2-yl)methyl-idene]benzene-1,4-di-amine (PQMBD) and HgCl2, the coordination sphere around the Hg(2+) atom is distorted tetra-hedral, comprising two Cl atoms [Hg-Cl = 2.3487?(14) and 2.4490?(15)?Å] and two N atom donors from the PQMBD ligand, viz. the quinolyl and the imine N atom [Hg-N = 2.270?(4) and 2.346?(4)?Å, respectively]. The dihedral angle between the two benzene rings attached to the amino group is 43.7?(3)°. In the crystal, N-H?Cl and C-H?Cl hydrogen bonds, as well as ?-? stacking inter-actions between one phenyl ring and the pyridine ring of the quinoline moiety of an adjacent mol-ecule [centroid-to-centroid separation = 3.617?(4)?Å] are observed, resulting in a three-dimensional network.

Chlorido{5-chloro-2-[2-(methyl-sulfanyl)phenyl-diazen-yl]phenyl}-platinum(II).

Project description:The title compound, [Pt(C(13)H(10)ClN(2)S)Cl], contains a Pt atom tetra-coordinated by a benzene C, a diazene N, a Cl and an S atom in an approximately square-planar geometry. The mol-ecules dimerize through a nonbonded S⋯S inter-action [S⋯S = 3.523 (18) Å]. There are no hydrogen bonds and the crystal packing is stabilized by four inter-molecular π-π inter-actions; the centroid-centroid distances are 3.804 (3), 3.638 (3), 3.804 (3) and 3.638 (3) Å, and the corresponding perpendicular distances are 3.369, 3.448, 3.406 and 3.466 Å.

Acetonyltri-phenyl-phospho-nium 2,3,5-tri-phenyl-tetra-zolium tetra-chlorido-cuprate(II).

Project description:The title compound, (C21H20OP)(C19H15N4)[CuCl4], was obtained by reacting CuCl2·2H2O with a mixture of one equivalent of acetonyltri-phenyl-phospho-nium chloride and one equivalent of 2,3,5-tri-phenyl-tetra-zolium chloride in aceto-nitrile. In the structure, the Cu centre in the dianion is bonded to four chloride ligands and adopts a distorted tetra-hedral geometry. The phospho-nium cation likewise adopts the expected tetra-hedral geometry. The tetra-zolium ring forms dihedral angles of 77.68 (10), 26.85 (11) and 66.48 (10)° with the planes of the benzene rings of the substituent groups. In the crystal, weak C-H⋯Cl hydrogen-bonding inter-actions involving both cations and the anion give rise to a three-dimensional supra-molecular structure.
