Crystal structure of di-chlorido-[2-(1H-imidazol-2-yl-?N (3))imidazolato-?N]bis-(tri-n-butyl-phosphane-?P)rhodium(III).

ABSTRACT: In the title compound, [Rh(C6H5N4)Cl2(C12H27P)2], the Rh(III) ion is chelated by the singly deprotonated 2,2'-biimidazolate (Hbim(-)) ligand and coordinated by two chloride ions and two tri-n-butyl-phosphane ligands. The chloride ions and N atoms of the Hbim(-) ligand lie in a plane where the sum of X-Rh-X angles between cis sites is 360°. The phosphane ligands occupy the sites perpendicular to the plane, completing the overall distorted octahedral coordination sphere. The complex forms a self-complementary hydrogen-bonded dimer with the inversion-related complex through N-H?N hydrogen bonds.

Crystal structure of bis-(2-methyl-1H-imidazol-3-ium) μ-oxalato-bis-[n-butyl-tri-chlorido-stannate(IV)].

Project description:The Sn(IV) atom in the centrosymmetric anion of the title salt, (C4H7N2)2[Sn2(C4H9)2(C2O4)Cl6], is coordinated in a distorted octa-hedral mode by two O atoms of a bridging oxalate moiety, three Cl atoms and a C atom of an n-butyl group. The latter is disordered over two sets of sites in a 0.66:0.33 occupancy ratio. N-H⋯O and N-H⋯Cl hydrogen bonds involving the 2-methyl-imidazolium cation and neighbouring anions result in the formation of chains extending parallel to [001].

Tri-methyl-phospho-nium trans-tetra-chlorido-bis-(tri-methyl-phosphane-κP)iridate(III).

Project description:The title compound, [HP(CH3)3][IrCl4{(H3C)3P}2], consists of a tri-methyl-phospho-nium cation and a tetra-chlorido-bis-(tri-methyl-phosphane)iridate(III) anion.

The Ir(III) atom sits on an inversion center with one P(CH3)3 ligand and two chloride ligands in the asymmetric unit. The tri-methyl-phospho-nium cation is disordered about a twofold rotation axis. The title compound is the first structurally characterized tetra-chlorido-bis-(phosphane)iridate complex.

Crystal structures of fac-tri-chlorido-tris-(tri-methyl-phosphane-?P)rhodium(III) monohydrate and fac-tri-chlorido-tris-(tri-methyl-phosphane-?P)rhodium(III) methanol hemisolvate: rhodium structures that are isotypic with their iridium analogs.

Project description:The crystal structures of two solvates of fac-tri-chlorido-tris-(tri-methyl-phosphane-?P)rhodium(III) are reported, i.e. one with water in the crystal lattice, fac-[RhCl3(Me3P)3]·H2O, and one with methanol in the crystal lattice, fac-[RhCl3(Me3P)3]·0.5CH3OH. These rhodium compounds exhibit distorted octahedral coordination spheres at the metal and are isotypic with the analogous iridium compounds previously reported by us [Merola et al. (2013 ?). Polyhedron, 54, 67-73]. Comparison is made between the rhodium and iridium compounds, highlighting their isostructural relationships.

Bis[?-1,3-bis-(1H-imidazol-1-yl)propane-?(2) N (3):N (3')]bis-(di-chlorido-zinc) dihydrate.

Project description:The title hydrated complex, [Zn2Cl4(C9H12N4)2]·2H2O, is a discrete dinuclear zinc complex with 1,3-bis-(1H-imidazol-1-yl)propane as the bridging ligand. The complex mol-ecule lies about a crystallographic inversion centre. The Zn(II) atom exhibits a distorted tetra-hedral coordination geometry defined by two imidazole N atoms and two Cl atoms. O-H?Cl hydrogen bonding between the lattice water mol-ecules and the terminal Cl atoms of the mol-ecule lead to a two-dimensional structure extending parallel to (100).

1,1'-[(Biphenyl-4,4'-di-yl)bis-(methyl-ene)]di-1H-imidazol-3-ium tetra-chlorido-mercurate(II).

Project description:In the title compound, (C(20)H(20)N(4))[HgCl(4)], the Hg(II) ion is four-coordinated in a tetra-hedral environment defined by four chloride ions. The dihedral angle between the two phenyl rings is 32.83?(15)°. The protonated 1,1'-[(biphenyl-4,4'-di-yl)bis-(meth-yl-ene)]di-1H-imidazol-3-ium cations, showing a cis conformation, link the [HgCl(4)](2-) anions into an R(4) (4)(42) motif via N-H?Cl hydrogen bonds.

Di-μ-chlorido-bis-(chlorido{2,2'-[3-(1H-imidazol-4-ylmeth-yl)-3-aza-pentane-1,5-di-yl]diphthalimide}copper(II)).

Project description:The centrosymmetric dinuclear Cu(II) complex, [Cu(2)Cl(4)(C(24)H(21)N(5)O(4))(2)], was synthesized by the reaction of CuCl(2)·2H(2)O with the tripodal ligand 2,2'-[3-(1H-imid-azol-4-ylmeth-yl)-3-aza-pentane-1,5-di-yl]diphthalimide (L). Each of the Cu(II) ions is coordinated by two N atoms from the ligand, two bridging Cl atoms and one terminal Cl atom. The Cu(II) coordination can be best be described as a transition state between four- and five-coordination, since one of the bridging Cl atoms has a much longer Cu-Cl bond distance [2.7069 (13) Å] than the other [2.2630 (12) Å]. In addition, the Cu⋯Cu distance is 3.622 (1) Å. The three-dimensional structrure is generated by N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.658 (4) and 4.020 (4) Å].

A triclinic polymorph of bis-(?-di-tert-butyl-phosphanido)bis-[(di-tert-butyl-phosphane)palladium(I)].

Project description:A new polymorph of the title compound, [Pd(2)(C(8)H(18)P)(2)(C(8)H(19)P)(2)], has been found. It belongs to the triclinic P-1 space group, whereas the known form [Leoni, Sommovigo, Pasquali, Sabatino & Braga (1992 ?), J. Organo-met. Chem.423, 263-270] crystallizes in the monoclinic C2/c space group. The title compound features a dinuclear palladium complex with a planar central Pd(2)(?-P)(2) core (r.m.s. deviation = 0.003?Å). The Pd-Pd distance of 2.5988?(5)?Å is within the range of a Pd(I)-Pd(I) bond. The mol-ecules of both polymorphs are located on a crystallographic centre of inversion. The mol-ecular conformations of the two polymorphs are essentially identical. The crystal packing patterns, on the other hand, are slightly different.

Bis(5-amino-4-amino-carbonyl-1H-imid-azol-3-ium) (5-amino-4-amino-carbonyl-1H-imidazol-3-ium-κO)-di-μ-chlorido-hepta-chlorido-dibismuth(III) mono-hydrate.

Project description:The title compound, (C(4)H(7)N(4)O)(2)[Bi(2)Cl(9)(C(4)H(7)N(4)O)]·H(2)O, was prepared by the reaction of bis-muth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-amino-carbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric biocta-hedral [Bi(2)C1(9)(C(4)H(7)N(4)O)](2-) dianion and a water mol-ecule. In the dianion, the planar 5-amino-4-amino-carbonyl-1H-imidazol-3-ium ligand occupies an equatorial site and is inclined at an angle of 75.7 (2)° to the Bi(2)(μ-C1)(2) plane. The salt forms a three-dimensional network arising from hydrogen bonds between cations, anions and water mol-ecules.

Di-chlorido-bis-[1-(2,4,6-tri-methyl-phen-yl)-1H-imidazole-κN (3)]copper(II).

Project description:In the title complex, [CuCl2(C12H14N2)2], the Cu(2+) cation is situated on an inversion centre and is coordinated by two N atoms from symmetry-related 1-mesityl-1H-imidazole ligands and by two chloride anions in a slightly distorted square-planar geometry. In the organic ligand, the dihedral angle between the benzene ring of the mesityl moiety and the imidazole ring is 76.99 (18)°. Weak intra-molecular C-H⋯Cl hydrogen-bonding inter-actions consolidate the mol-ecular conformation.

Chlorido(1H-imidazole-?N)bis-(triphenyl-phosphane-?P)copper(I).

Project description:In the title complex, [CuCl(C(3)H(4)N(2))(C(18)H(15)P)(2)], the coordination geometry around Cu(I) is distorted tetra-hedral formed by two triphenyl-phosphane ligands, an imidazole ligand and a chloride group. An intra-molecular C-H?Cl inter-action occurs. The crystal packing is stabilized by inter-molecular N-H?Cl hydrogen bonds, which form an extended chain parallel to [010].
