Tetra-?-acetato-?O:O'-bis-{[N-(4-methyl-phen-yl)pyridin-2-amine-?N]copper(II)}(Cu-Cu).

ABSTRACT: The complete dinuclear mol-ecule of the title complex, [Cu(2)(CH(3)COO)(4)(C(12)H(12)N(2))(2)], is generated by a centre of inversion. The Cu(II) atoms are connected [Cu-Cu = 2.6329?(16)?Å] and bridged by four acetate ligands. The distorted octa-hedral coordination geometry is completed by a terminal pyridine N atom. The amine H atom forms an intra-molecular N-H?O hydrogen bond.

Tetra-μ-acetato-κO:O'-bis-{[4-methyl-N-(4-methyl-phen-yl)pyridin-2-amine-κN]copper(II)}.

Project description:The title complex, [Cu(2)(CH(3)COO)(4)(C(13)H(14)N(2))(2)], features a binuclear mol-ecule, which lies about a crystallographic centre of inversion; the four acetate ions each bridge a pair of Cu(II) atoms. The coordination of the metal atom is distorted octa-hedral within a donor set defined by four O atoms, the heterocyclic N atom and the second Cu atom. The pyridine ring is twisted with respect to the tolyl ring and forms a dihedral angle of 35.34 (9)°. A bifurcated N-H⋯(O,O) hydrogen bond is present, linking the amine group to two carboxyl-ate O atoms derived from different acetate ions. In the crystal, C-H⋯π inter-actions link mol-ecules into a supra-molecular array in the bc plane.

Project description:In the crystal structure of the title complex, [Cu(2)(CH(3)COO)(4)(C(12)H(11)ClN(2))(2)], the complete binuclear mol-ecule is generated by a crystallographic centre of inversion; the four acetate groups each bridge a pair of Cu(II) atoms. The coordination of the metal atom is distorted octa-hedral within a donor set defined by four O atoms, the heterocyclic N atom and the second Cu atom. The pyridine ring is twisted with respect to the benzene ring, forming a dihedral angle of 33.9 (2)°. An intra-molecular N-H⋯O hydrogen bond is present between the amino group and a carboxyl O atom. Inter-molecular inter-actions of the C-H⋯π type link mol-ecules in the crystal structure.

Tetra-?-acetato-?O:O'-bis-{[2,2-dimeth-yl-N-(pyridin-2-yl)propanamide-?N]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.

Diaqua-bis[2-(4-bromo-phen-yl)acetato]bis-(N,N-dimethyl-pyridin-4-amine)copper(II).

Project description:In the title compound, [Cu(C(8)H(6)BrO(2))(2)(C(7)H(10)N(2))(2)(H(2)O)(2)], the Cu(II) atom (site symmetry ) adopts a Jahn-Teller-distorted trans-CuN(2)O(4) octa-hedral coordination, with the aqua O atoms in axially extended sites. An intra-molecular O-H?O hydrogen bond helps to establish the conformation and an inter-molecular O-H?O hydrogen bond is seen in the crystal packing.

Tetra-μ-acetato-κO:O'-bis-[(N-ethyl-pyrimidin-2-amine)-copper(II)](Cu-Cu).

Project description:In the centrosymmetric title mol-ecule, [Cu(2)(CH(3)COO)(4)(C(6)H(9)N(3))(2)], each of the four acetate groups bridges a pair of Cu(II) atoms [Cu-Cu = 2.6540 (4) Å]. The distorted octa-hedral geometry of the metal atom is completed by an N-donor atom of the N-ethyl-pyrimidin-2-amine ligand: an intra-molecular N-H⋯O hydrogen links its N-H group to an acetate carboxyl-ate O atom. In the crystal, C-H⋯O inter-actions link the mol-ecules into a supra-molecular chain along the b axis.

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)°.
