Synthesis and Characterization of a Binuclear Copper(II)-dipyriamethyrin Complex: [Cu₂(dipyriamethyrin)(?₂-1,1-acetato)₂].

ABSTRACT: The reaction between dipyriamethyrin and copper(II) acetate [Cu(OAc)₂] afforded what is, to our knowledge, the first transition metal-dipyriamethyrin complex. Molecular and electronic characterization of this binuclear Cu(II) complex via EPR, UV-vis, and single crystal X-ray diffraction analysis revealed marked differences between the present constructs and previously reported binuclear copper(II) hexaphyrin species. UV-vis titration analyses provided evidence for a homotropic positive allosteric effect, wherein the binuclear species is formed without significant intermediacy of a monomeric complex.

Selective DNA strand scission with binuclear copper complexes: implications for an active Cu2-O2 species.

Project description:A homologous series of binuclear copper(II) complexes [Cu(II)(2)(Nn)(Y)(2)](2+) (1-3) (n = 3-5 and Y = (ClO(4))(-) or (NO(3))(-)) were studied to investigate the intermediate(s) responsible for selective DNA strand scission in the presence of MPA/O(2) (MPA = 3-mercaptopropanoic acid). While the N3 complex does not react, the N4 and N5 analogues show comparable activity with strand scission occurring at a single-strand/double-strand junction. Identical reactivity is also observed in the alternate presence of H(2)O(2). Spectroscopic and reactivity studies with [Cu(II)(2)(N4)(Y)(2)](2+) (2) and H(2)O(2) are consistent with DNA oxidation mediated by formation of a side-on peroxodicopper(II) (Cu(2)-O(2)) complex.

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.

Di-?-acetato-bis-[(acetato-?O,O')bis-(iso-nicotinamide-?N)copper(II)].

Project description:The title centrosymmetric bimetallic complex, [Cu(2)(C(2)H(3)O(2))(4)(C(6)H(6)N(2)O)(4)], is composed of two copper(II) cations, four acetate anions and four isonicotinamide (INA) ligands. The asymmetric unit contains one copper cation to which two acetate units bind asymmetrically; one of the Cu-O distances is rather long [2.740?(2)?Å], almost at the limit of coordination. These Cu-O bonds define an equatorial plane to which the Cu-N bonds to the INA ligands are almost perpendicular, the Cu-N vectors subtending angles of 2.4?(1) and 2.3?(1)° to the normal to the plane. The metal coordination geometry can be described as a slightly distorted trigonal bipyramid if the extremely weak Cu-O bond is disregarded, or as a highly distorted square bipyramid if it is not. The double acetate bridge between the copper ions is not coplanar with the CuO(4) equatorial planes, the dihedral angle between the (O-C-O)(2) and O-Cu-O groups being 34.3?(1)°, resulting in a sofa-like conformation for the 8-member bridging loop. In the crystal, N-H?O hydrogen bonds occur, some of which generate a head-to tail-linkage between INA units, giving raise to chains along [101]; the remaining ones make inter-chain contacts, defining a three-dimensional network. There are in addition a number of C-H?O bonds involving aromatic H atoms. Probably due to steric hindrance, the aromatic rings are not involved in significant ??? inter-actions.

Crystal structure of bis-(μ2-meth-anolato-κO:κO)hexa-methyl-bis-(μ2-tri-phenyl-acetato-κO:κO')bis-(μ2-tri-phenyl-acetato-κ2 O,O':κO)dialuminiumdi-lanthanum toluene tetra-solvate.

Project description:The title compound, [Al2La2(C20H15O2)4(CH3)6(CH3O)2]·4CH3C6H5 or [{La(Ph3CCOO)2(Me3AlOMe)}2]·4CH3C6H5, was formed in a reaction between lanthanum tris-(tetra-methyl-aluminate) and tri-phenyl-acetic acid (1:1) with unintended partial oxidation. The tri-phenyl-acetate ligand exhibits μ2-κ1 O:κ1 O' bridging and μ2-κ2 O,O':κ1 O semi-bridging coordination modes, forming a dimeric La2(μ-OCO)4 core. The semi-bridging tri-phenyl-acetate group provides additional bonding with an La3+ cation via the π-system of one of its phenyl rings. The tri-methyl-meth-oxy-aluminate anion, which is coordinated to the La3+ cation by its O atom, displays a rather long La-CMe bond. Two toluene mol-ecules are each disordered over two orientations about centres of symmetry with site occupancy factors of 0.5. The title compound represents the first example of an LnIII complex containing both alkyl alkoxide aluminate and π-bounded arene fragments.

Dibromido[1,1'-dibutyl-2,2'-(pentane-1,1-di-yl)di-1H-benzimidazole]-copper(II).

Project description:In the title compound, [CuBr(2)(C(27)H(36)N(4))], the Cu(II) ion exhibits a distorted tetra-hedral coordination geometry provided by two bromide ions and by chelation of two imine N-atom donors from a bis-(benzimidazole) ligand. Chelation results in a six-membered boat-shaped ring which links the benzimidazole groups. Each bis-(benzimidazole) fragment contains three n-butyl substituents, two of which have the expected trans conformation; the third exhibits the higher-energy cis conformation, an orientation consistent with several short intra-molecular C-H⋯Br inter-actions. Essentially planar (r.m.s. deviations of 0.0101 and 0.0183 Å) benzimidazole groups are oriented so as to give the bis-(benzimidazole) fragment a V-shaped appearance in profile with the cis and trans n-butyl groups directed to opposite sides of the planes. In the crystal, columns of mol-ecules along the b-axis direction form layers parallel to the (202) planes. Within a given column, the mol-ecules are linked by C-H⋯Br hydrogen bonds. The mol-ecules in adjacent columns are also linked by inter-molecular C-H⋯π interactions, forming a three-dimensional network.

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.

Crystal structure of a tetranuclear Cu(II) complex with an O,N,N'-donor Schiff base ligand: hexa-μ2-acetato-bis-(2-{[(2,2,6,6-tetra-methyl-piperidin-4-yl)imino]-meth-yl}phenolato-κ(3) O,N,N')tetra-copper(II).

Project description:The title compound, [Cu4(CH3COO)6(C16H23N2O)2], lies across a twofold rotation axis. The asymmetric unit contains two independent Cu(II) ions. The symmetry-unique terminal Cu(II) ion is O,N,N'-coordinated by a 2-{[(2,2,6,6-tetra-methyl-piperidin-4-yl)imino]-meth-yl}phenolate ligand and an O atom from an acetate group in a slightly distorted square-planar coordination environment. The symmetry-unique central Cu(II) ion is coordinated by a different O atom from the same acetate group and by four bridging acetate ligands, which connect the asymmetric unit into a dimeric complex and form a distorted square-pyramidal coordination environment. Within the complex there are two symmetry-equivalent intra-molecular N-H⋯O hydrogen bonds. In the crystal, weak C-H⋯O hydrogen bonds link the complex mol-ecules, forming a three-dimensional network.

catena-Poly[bis-(μ3-2-phenyl-acetato-κ(3) O,O':O)bis-(μ2-2-phenyl-acetato-κ(2) O:O')dicopper(II)(Cu-Cu)].

Project description:The title polymeric compound, [Cu2(C8H7O2)4] n , was synthesized by the reaction of copper acetate with aqueous phenyl-acetic acid. The unique Cu(II) atom is coordinated by five O atoms from the carboxyl-ate groups of phenyl-acetate ligands, and the strongly distorted octa-hedral coordination environment is completed by a Cu-Cu bond of 2.581 (2) Å, at whose mid-point is located an inversion centre. The crystal structure consists of infinite polymeric linear chains of Cu(2+) ions, running along [100], linked by bridging phenyl-acetate groups.
