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

ABSTRACT: 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 ?-? stacking between isoquinoline ring systems.

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-kis(?-3,4-dimethoxy-phenyl-acetato)bis-[(3,4-dimethoxy-phenyl-acetato)(1,10-phenanthroline)dysprosium(III)].

Project description:The title centrosymmetric dinuclear dysprosium(III) complex, [Dy(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)] or [Dy(L)(3)phen](2), is comprised of six 3,4-dimethoxy-phenylacetate (L) anions, two 1,10-phenanthroline (phen) mol-ecules and two Dy(III) ions. The Dy(III) atom is nine-coordinated by seven O atoms from five L ligands and two N atoms from the phen mol-ecules. The L ligands are coordinated to the Dy(III) ion in three coordination modes: chelating, bridging and bridging-tridentate. C-H?O hydrogen bonding interactions consolidate the crystal packing.

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.

Tetra-kis(?-naphthalene-1-acetato-?O:O')bis-[(N,N-dimethyl-formamide-?O)copper(II)].

Project description:The asymmetric unit of the title compound, [Cu(2)(C(12)H(9)O(2))(4)(C(3)H(7)NO)(2)], contains two independent centrosymmetric dinuclear copper(II) complexes. The central paddle-wheel units are formed by four bridging bidentate naphthalene-1-acetate ligands with two dimethyl-formamide ligands in the axial positions. The unique Cu(II) ions have slightly distorted square-pyramidal coordination geometries. One of the naphthalene rings is disordered over two sets of sites, with refined occpancies of 0.535?(4) and 0.465?(4).

Tetra-kis(μ-3,4-dimeth-oxy-phenyl-acetato)-bis-[(3,4-dimeth-oxy-phenyl-acetato)(1,10-phenanthroline)holmium(III)].

Project description:In the centrosymmetric title compound, [Ho(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Ho(III) atom is nine-coordinated by seven O atoms from the 3,4-dimeth-oxy-phenyl-acetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) mol-ecule. The L ligands are coordinated to the Ho(III) ions in three modes: chelating, bridging and bridging-tridentate. Intra-molecular C-H⋯O inter-actions occur. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions and weak aromatic π-π inter-actions between phen mol-ecules and the aromatic rings of the L ligands [centroid-centroid distance = 3.821 (2) Å].

Project description:The title compound, [Co2(C8H7O2)4(C7H10N2)2], crystallizes as a centrosymmetric dimer containing two Co(II) atoms bridged by four bidentate phenyl-acetate ligands in syn-syn bridging modes. Each Co(II) atom is five-coordinated by four O atoms from four different carboxyl-ate ligands and the ring N atom of a 4-(di-methyl-amino)-pyridine unit, generating a distorted square-pyramidal geometry in which the four O atoms form the basal plane and the N atom occupies the axial position.

Bis(?-2-phenyl-acetato-?O:O)bis-[(2,2'-bipyridyl-?N,N')(2-phenyl-acetato-?O)copper(II)] dihydrate.

Project description:The mol-ecule of the binuclear title complex, [Cu(2)(C(8)H(7)O(2))(4)(C(10)H(8)N(2))(2)]·2H(2)O, is located on an inversion centre. The Cu atoms are bridged by two O atoms of the monodentate phenyl-acetate groups [Cu-O = 1.9808?(14) and 2.3668?(14)?Å]. The longer of the two bridging Cu-O bonds takes the apical position of the distorted square-pyramidal environment of the Cu atom, which is completed by two N atoms of the chelate 2,2'-bipyridine ligand [Cu-N = 2.0107?(17) and 2.0234?(16)?Å]. The mol-ecules are assembled into stacks along [100] through ?-? inter-actions with inter-planar distances of 3.630?(4) and 3.407?(3)?Å; the resulting stacks are further connected into a three-dimensional supra-molecular architecture by O-H?O and C-H?O hydrogen-bonding inter-actions.

Tetra-kis(?-2-phenyl-quinoline-4-carboxyl-ato-?(2)O:O')bis-[(methanol-?O)copper(II)].

Project description:The title complex, [Cu(2)(C(16)H(10)NO(2))(4)(CH(3)OH)(2)], consists of centrosymmetric wheel-shaped dinuclear neutral mol-ecules in which each Cu(II) atom is coordinated in a slightly distorted square-pyramidal geometry by four O atoms of carboxyl-ate groups from different ligands at the basal plane and an O atom of a methanol mol-ecule at the axial position. In the crystal, the dinuclear complex mol-ecules are linked into one-dimensional supra-molecular columns parallel to the b axis by O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.7259?(11)?Å].

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)°.
