Crystal structure of catena-poly[[chlorido-(4,4'-dimethyl-2,2'-bi-pyridine-?(2) N,N')copper(II)]-?-chlorido].

ABSTRACT: The title compound, [CuCl2(C12H12N2)] n , was obtained via a DMSO-mediated dehydration of Cu(4,4'-dimethyl-2,2'-bi-pyridine)-copper(II)·0.25H2O. The central Cu(II) atom is coordinated in a distorted trigonal-bipyramidal geometry by two N atoms of a chelating 4,4'-dimethyl-2,2'-bi-pyridine ligand [average Cu-N = 2.03?(3)?Å] and three Cl atoms, one terminal with a short Cu-Cl bond of 2.2506?(10)?Å, and two symmetry-equivalent and bridging bonds. The bridging Cl atom links the Cu(II) ions into chains parallel to [001] via one medium and one long Cu-Cl bond [2.3320?(10) and 2.5623?(9)?Å]. The structure displays both inter- and intra-molecular C-H?Cl hydrogen bonding.

The title compound, [CuCl2(C12H12N2)] n , was obtained via a DMSO-mediated dehydration of Cu(4,4'-dimethyl-2,2'-bi-pyridine)-copper(II)·0.25H2O. The central Cu(II) atom is coordinated in a distorted trigonal-bipyramidal geometry by two N atoms of a chelating 4,4'-dimethyl-2,2'-bi-pyridine ligand [average Cu-N = 2.03 (3) Å] and three Cl atoms, one terminal with a short Cu-Cl bond of 2.2506 (10) Å, and two symmetry-equivalent and bridging bonds.

Project description:In the title compound, [Cu(3)(CN)(3)(C(12)H(12)N(2))(2)], two 2,2'-bipyridine N,N'-chelated Cu(I) atoms are linked by a cyanide bridge that lies about a center of inversion; the Cu(I) atom exists in a tetra-hedral coordination geometry. This dinuclear entity is linked to another Cu(I) atom that lies on a twofold rotation axis by another cyanide bridge, these bridges giving rise to the formation of a linear chain motif.

Project description:The title compound, [PdCl2(C18H24N2)]·(CH3)2SO·H2O, the Pd(II) ion is in a distorted square-planar geometry. The Pd-N bond distances are 2.022?(2) and 2.027?(2)?Å, the Pd-Cl bond distances are 2.2880?(7) and 2.2833?(7)?Å, and the ligand bite angle is 80.07?(9)°. The dimethyl sulfoxide and water mol-ecules form linear chains along [100] by O-H?O and O-H?S hydrogen bonds, generating eight- and 12-membered rings.

(2,2'-Bi-pyridine-κ(2) N,N')tetra-kis-(dimethyl sulfoxide-κO)copper(II) bis-(perchlorate).

Project description:The title compound, [Cu(C2H6OS)4(C10H8N2)](ClO4)2, contains a Cu(II) ion with a distorted octa-hedral coordination environment, bonded by four O atoms of the monodentate dimethyl sulfoxide ligands and two N atoms of the bidentate chelating 2,2'-bi-pyridine ligand. The equatorial Cu-N and Cu-O bond lengths are in the range 1.979 (2)-1.998 (3) Å. The axial Cu-O bond distances are 2.365 (2) and 2.394 (2) Å. In the crystal, the complex cations and perchlorate anions are connected by numerous C-H⋯O hydrogen bonds, which leads to additional stabilization of the structure. The perchlorate anion is disordered over two sets of sites with a 0.716 (3):0.284 (3) occupancy ratio.
