Crystal structure of μ-oxalodi-hydroxamato-bis-[(2,2'-bipyrid-yl)(di-methyl sulfoxide-κO)copper(II)] bis-(perchlorate).

ABSTRACT: The centrosymmetric binuclear complex, [Cu2(C2H2N2O4)(C10H8N2)2(C2H6OS)2](ClO4)2, contains two copper(II) ions, connected through an N-deprotonated oxalodi-hydroxamic acid dianion, two terminal 2,2'-bi-pyridine ligands, and two apically coordinating dimethylsulfoxide mol-ecules. Two non-coordinating perchlorate anions assure electrical neutrality. The copper(II) ions in the complex dication [Cu2(C10H8N2)2(μ-C2H2N2O4)(C2H6SO)2](2+) are in an O2N3 square-pyramidal donor environment, the Cu-Cu separation being 5.2949 (4) Å. Two hydroxamate groups in the deprotonated oxalodi-hydroxamic acid are located trans to one each other. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the complex cations to the perchlorate anions. Further C-H⋯O hydrogen bonds combine with π-π contacts with a centroid-to-centroid separation of 3.6371 (12) Å to stack the mol-ecules along the a-axis direction.

(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.

Project description:In the title compound, [Cu(NO(3))(C(10)H(8)N(2))(2)]ClO(4), the five-coordinated Cu(II) atom has a distorted square-pyramidal CuN(4)O environment; the O atom is in the axial position whereas the N atoms from two bipyridine (bipy) ligands are in the equatorial plane.

The nitrite anion is equally disordered over two sets of sites.

Project description:The title compound, [V(2)F(2)O(4)(C(10)H(8)N)(2)], is a centrosymmetric binuclear vanadium(V) species with the metal ions in a distorted octa-hedral environment. The coordination geometries of the symmetry-equivalent V(V) atoms are defined by cis-terminal fluoride and oxide groups, unsymmetrically bridging oxide groups and the N-atom donors of the bipyridyl ligand. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯F hydrogen bonds.

μ-Oxalato-bis-[(2,2'-bipyridyl)-copper(II)] bis(perchlorate) dimethyl-formamide disolvate monohydrate.

Project description:The title compound, [Cu(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·2C(3)H(7)NO·H(2)O, contains doubly charged centrosymmetric dinuclear oxalato-bridged copper(II) complex cations, perchlorate anions, and DMF and water solvate mol-ecules. In the complex cation, the oxalate ligand is coordinated in a bis-bidentate bridging mode to the Cu atoms. Each Cu atom has a distorted tetra-gonal-bipyramidal environment, being coordinated by two N atoms of the two chelating bipy ligands and two O atoms of the doubly deprotonated oxalate anion. Pairs of perchlorate anions and water mol-ecules are linked into recta-ngles by O-H⋯O bonds in which the perchlorate O atoms act as acceptors and the water mol-ecules as donors. Methyl groups of the DMF solvent molecule are disordered over two sites with occupancies of 0.453 (7):0.547 (7), and the water molecule is half-occupied.

Bis{μ-2,2'-[(3-aza-pentane-1,5-di-yl)bis-(nitrilo-methyl-idyne)]diphenolato}dicopper(II) dimethyl sulfoxide disolvate.

Project description:The title compound, [Cu(2)(C(18)H(19)N(3)O(2))(2)]·2C(2)H(6)OS or [Cu(2)(SalenN(3)H)(2)]·2DMSO, where SalenN(3)H is the multidentate Schiff base 2,2'-[(3-aza-pentane-1,5-di-yl)bis-(nitrilo-methyl-idyne)]diphenolate dianion and DMSO is dimethyl sulfoxide, is a solvated dinuclear Cu(II) complex. The neutral complex is built from two Cu(SalenN(3)H) units related by an inversion center. All heteroatoms in the Schiff bases coordinate the Cu(II) ions, which display highly distorted trigonal bipyramidal geometries. The solvent mol-ecules are located in the structural voids of the complex and are disordered over two positions with occupancies of 0.642 (15) and 0.358 (15). The previously characterized acetone disolvate of the same complex presents identical mol-ecular and crystal structures, and crystallizes with cell parameters very close to those of the DMSO disolvate reported here.

Octa-methyl-bis-(μ(2)-2-methyl-benzoato-κO:O')bis-(2-methyl-benzoato-κO)di-μ(3)-oxido-tetra-tin(IV).

Project description:The title compound, [Sn(4)(CH(3))(8)(C(8)H(7)O(2))(4)O(2)], is a distann-oxane derivative of 2-methyl-benzoic acid. The crystal structure is composed of centrosymmetric dimers lying about inversion centres. Both independent Sn atoms adopt distorted trigonal-bipyramidal SnC(2)O(3) coordination geometries with the basal planes consisting of two C-atoms from the methyl groups and a bridging O atom. The Sn-C and Sn-O bond lengths lie in the ranges 2.090 (2)-2.104 (3) and 2.0241 (14)-2.2561 (15) Å, respectively. The central four-membered planar Sn(2)O(2) ring [Sn⋯Sn distance = 3.2993 (2) Å] makes dihedral angles of 5.43 (11) and 59.50 (7)° with the methyl-phenyl groups, which are themselves oriented at a dihedral angle of 61.38 (8)°. Besides weak C-H⋯O and C-H⋯π inter-actions, the packing mainly features van der Waals forces between the mol-ecules.

Di-μ(2)-chlorido-bis-[aqua-(2,2'-bipyridine-4,4'-dicarboxylic acid-κN,N')(nitrato-κO)copper(II)].

Project description:In the title compound, [Cu(2)Cl(2)(NO(3))(2)(C(12)H(8)N(2)O(4))(2)(H(2)O)(2)], which consists of a chloride-bridged Cu(II) dimer, the Cu atom is in a distorted octa-hedral environment defined by two N atoms from the 2,2'-bipyridine-4,4'-dicarboxylic acid ligand (H(2)bpdca), two bridging chlorido ligands, and two O atoms from an equatorial water mol-ecule and an axial nitrate anion, respectively. The two halves of the dimeric unit are related by an inversion centre at the midpoint between the two Cu atoms. Both carboxylic acid groups in the H(2)bpdca ligand remain protonated, as confirmed by the two sets of C-O bond lengths. The dinuclear mol-ecules are linked into a three-dimensional network via inter-molecular hydrogen bonds.

Two ethanol mol-ecules coordinate the Cu atoms in apical positions, giving an overall square-pyramidal coordination geometry. The Cu⋯Cu separation is 2.600 (1) Å. In the crystal, mol-ecules are assembled into chains extending in [001] through O-H⋯O hydrogen bonds.
