Tetra-?-acetato-bis-{[9-(pyrazin-2-yl)-9H-carbazole]copper(II)}.

ABSTRACT: The title complex, [Cu(2)(CH(3)COO)(4)(C(16)H(11)N(3))(2)], lies on an inversion centre, with four acetate ligands bridging two symmetry-related Cu(II) ions and two monodentate 9-(pyrazin-2-yl)-9H-carbazole ligands coordinating each Cu(II) ion via the N atoms of the pyrazine rings, forming slightly distorted square-pyramidal geometries. There are weak ?-? stacking inter-actions between the pyrrole rings of symmetry-related mol-ecules, with a centroid-to-centroid distance of 3.692?(2)?Å.

Tetra-imidazole-bis(trichloro-acetato)copper(II).

Project description:The title compound, [Cu(C(2)Cl(3)O(2))(2)(C(3)H(4)N(2))(4)], was prepared by the reaction of imidazole and trichloro-acetatocopper(II). The Cu(II) atom adopts a distorted octa-hedral coordination geometry, binding the N atoms of four imidazole ligands and the carboxyl-ate O atoms of two trichloro-acetate anions. The mol-ecular structure and packing are stabilized by N-H?O hydrogen-bonding inter-actions. Close inter-molecular Cl?Cl contacts [3.498?(3)?Å] are also found in the structure.

9-Phenyl-3,6-bis-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)-9H-carbazole.

Project description:In the title compound, C(30)H(35)B(2)NO(4), the carbazole skeleton is essentially planar (r.m.s. deviation for all non-H atoms = 0.035?Å), and is oriented at a dihedral angle of 65.0?(3)° with respect to the adjacent phenyl ring.

Tetra-?-acetato-bis-[(1,3-benzothia-zole)copper(II)](Cu-Cu).

Project description:The title compound, [Cu(2)(CH(3)CO(2))(4)(C(7)H(5)NS)(2)] or [(C(7)H(5)NS)Cu](2)(?-O(2)CCH(3))(4), crystallizes with one mol-ecule per unit cell. The coordination number of copper is six with four basal O atoms, one axial N atom and one axial Cu atom. Four acetate ligands act as bidentate linker and connect two Cu atoms, with a crystallographic inversion center located at the mid-point of the Cu-Cu bond. The acetate ligands form slightly distorted square planes around each metal ion, while the copper ions are displaced by 0.2089?(4)?Å from these planes towards the N atoms. Thus, the Cu-Cu distance is elongated to 2.6378?(7)?Å, compared with the 2.2180?(7)?Å distance between the two basal planes. The angle between the basal plane and the Cu-N bond is 4.84?(6)°.

Tetra-?(2)-acetato-?O:O'-bis-[(isoquinoline-?N)copper(II)].

Project description:In the crystal structure of the title compound, [Cu(2)(CH(3)COO)(4)(C(9)H(7)N)(2)], the Cu(II) cation is coordinated by four acetate anions and one isoquinoline mol-ecule in a distorted square-pyramidal geometry; the Cu(II) cation is 0.1681?(6)?Å from the basal coordination plane formed by the four O atoms. Each acetate anion bridges two Cu(II) cations to form the centrosymmetric dinuclear complex. Within the dinuclear mol-ecule, the Cu?Cu separation is 2.6459?(4)?Å. A parallel arrangement of isoquinoline ligands of adjacent complexes is observed in the crystal structure; the face-to-face distance of 3.610?(10)?Å suggests there is no ?-? stacking between isoquinoline ring systems.

Tetra-?-acetato-bis-[(pyridine N-oxide)copper(II)](Cu-Cu).

Project description:The mol-ecule of the title binuclear copper(II) complex, [Cu(2)(CH(3)COO)(4)(C(5)H(5)NO)(2)], occupies a special position on a crystallographic inversion centre; the coordination environment of the Cu(II) atom is slightly distorted square-pyramidal and is made up of four O atoms belonging to four acetate groups in the basal plane with the O atom of pyridine N-oxide ligand in the apical position. The Cu-Cu distance is 2.6376?(6)?Å.

Tetra-?-acetato-?O:O'-bis-{[2-(2-fur-yl)-1-(2-furylmeth-yl)-1H-benzimidazole-?N]copper(II)}.

Project description:The title complex, [Cu(2)(CH(3)COO)(4)(C(16)H(12)N(2)O(2))(2)], forms a dimer of the paddle-wheel type located on a crystallographic inversion centre. The two Cu(II) atoms [Cu?Cu = 2.7254?(11)?Å] are bridged by four acetate anions. The geometry of the polyhedron around the metal centre can be described as tetra-gonal-pyramidal derived from the calculation of the value ? = 0.0018. The apical positions of the tetra-gonal-pyramidal copper coordination polyhedra are occupied by the N atoms of 2-(2-fur-yl)-1-(2-furylmeth-yl)-1H-benzimidazole ligands. In the crystal structure, mol-ecules are linked into a chain by inter-molecular C-H?O hydrogen bonds parallel to [010]. Two furan rings are disordered over two positions in ratios of 0.55:0.45 and 0.69:0.31.

Di-aqua-bis-[5-(2-pyrazin-2-yl)tetra-zolato]copper(II)-pyrazine-2-carbo-nitrile (1/2).

Project description:The title compound, [Cu(C5H3N6)2(H2O)2]·2C5H3N3, is a 1:2 co-crystal between the mononuclear complex di-aqua-bis-[5-(pyrazin-2-yl)tetra-zolato]copper(II) and the reagent pyrazine-2-carbo-nitrile which was used in the synthesis. The Cu(II) atom is located on an inversion centre and has a distorted octa-hedral [4 + 2]-coordination environment formed by four N atoms of two chelating bidentate 5-(pyrazin-2-yl)tetra-zolate ligands at shorter distances and two water O atoms at longer distances. The Cu(II) complex molecules are held together by O-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance 3.6139 (8) Å], forming layers parallel to (100). These layers alternate with layers of pyrazine-2-car-bo-nitrile mol-ecules and both are held together via C-H⋯N hydrogen bonds and further π-π stacking inter-actions.

Tetra-μ-acetato-κO:O'-bis-{[2,2-dimeth-yl-N-(pyridin-2-yl)propanamide-κN]copper(II)}(Cu-Cu).

Project description:The crystal structure of the title compound, [Cu(2)(C(2)H(3)O(2))(4)(C(10)H(14)N(2)O)(2)], reveals a dinuclear Cu(II) complex located about a center of inversion. The coordination environment of each Cu(II) cation is distorted octa-hedral, composed of four bridging acetate ligands, an apical pyridine donor and is completed by a Cu-Cu bond. The amide H atom forms intra-molecular hydrogen bonds to two carboxyl O atoms. In the crystal, weak inter-molecular pyridine-amide C-H⋯O inter-actions are also present.

Tetra-aqua-bis-[4-(pyrazin-2-ylsulfanylmeth-yl)benzoato]manganese(II) dihydrate.

Project description:The title compound, [Mn(C(12)H(9)N(2)O(2)S)(2)(H(2)O)(4)]·2H(2)O, has been synthesized with a flexible asymmetrical bridging ligand, 4-(pyrazin-2-ylsulfanylmeth-yl)benzoic acid (Hpztmb). The Mn(II) ion exhibits a centrosymmetric octa-hedral geometry involving two carboxyl-ate O atoms of two different pztmb ligands and four O atoms of four coordinated water mol-ecules. The packing shows a three-dimensional supra-molecular network via O-H?O and O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.884?(8) and 4.034?(8)?Å] between the benzene ring of one pztmb anion and the pyrazine ring of an adjacent anion.
