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

ABSTRACT: 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.

Tetra-μ-acetato-κO:O'-bis-[(3,5-di-methyl-1H-pyrazole-κN)-copper(II)].

Project description:The dinuclear centrosymmetric title compound, [Cu(2)(CH(3)CO(2))(4)(C(5)H(8)N(2))(2)], has a distorted square-pyramidal coordination geometry around each Cu(II) atom in which four O atoms from the bridging acetate ligands form the basal plane while two N atoms from the pyrazole ligands occupy the apical positions. The crystal has two half mol-ecules in the asymmetric unit with a Cu⋯Cu distance of 2.6762 (4) Å. Disorder was found for two O atoms and two C atoms of one acetate ligand and refined with occupancies of 0.265 (7) and 0.735 (7). The crystal also features mol-ecules linked through two N-H⋯O hydrogen bonds resulting in one-dimensional chains extending along the crystallographic b axis.

Tetra-μ(2)-acetato-κO:O'-bis-[(isoquinoline-κN)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 π-π stacking between isoquinoline ring systems.

Tetra-μ-acetato-κO:O'-bis-{[4-methyl-2-(m-tolyl-amino)pyridine-κN]copper(II)}.

Project description:In the crystal structure of the title binuclear complex, [Cu(2)(CH(3)COO)(4)(C(13)H(14)N(2))(2)], the four acetate groups each bridge a pair of Cu(II) atoms. The coordination of the metal atoms is distorted square-pyramidal, with the bonding O atoms comprising a square basal plane and the coordinating N atom of the N-heterocycle occupying the apical position. In the two N-hetercycle ligands, the benzene rings are twisted with respect to the pyridine rings, making dihedral angles of 53.1 (2) and 54.2 (2)°. Intra-molecular N-H⋯O hydrogen bonding is present between the imino and carb-oxy groups. The crystal studied was a non-merohedral twin with a minor twin component of 21.4%.

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.

Tetra-kis(μ(2)-phenyl-acetato-κO:O')bis-[(isoquinoline-κN)copper(II)].

Project description:In the title centrosymmetric binuclear Cu(II) complex, [Cu(2)(C(8)H(7)O(2))(4)(C(9)H(7)N)(2)], the two Cu cations are bridged by four carboxyl-ate groups of the phenyl-acetate anions; each Cu cation is further coordinated by an isoquinoline ligand to complete the distorted CuO(4)N square-pyramidal geometry. The Cu cation is displaced by 0.2092 (8) Å from the basal plane formed by the four O atoms. Within the dinuclear mol-ecule, the Cu⋯Cu separation is 2.6453 (6) Å. Although a parallel, overlapped arrangement of isoquinoline ligands exists in the crystal structure; the longer face-to-face distance of 3.667 (5) Å suggests there is no π-π stacking between isoquinoline ring systems.
