Bis(acetyl-acetonato-?O,O')[copper(II)nickel(II)(0.31/0.69)]: a mixed-metal complex.

ABSTRACT: The title complex, [Cu(0.31)Ni(0.69)(C(5)H(7)O(2))(2)], was isolated from the reaction of bis-(N,N-dimethyamino-ethanol)copper(II) with bis-(acetyl-acetonato)nickel(II), which yielded crystals with mixed sites at the central metal position; the refined copper-nickel occupancy ratio is 0.31?(4):0.69?(4). Two acetyl-acetonate ligands, related by a centre of symmetry, are coordinated to the central metal atom in a square-planar configuration while the methyne C atoms of the acetyl-acetonate ligands, ca 3.02?Å away, are orthogonal to this plane at the metal site.

(Acetyl-acetonato)(dicyanamido)(1,10-phenanthroline)copper(II) dihydrate.

Project description:In the title compound, [Cu(C(5)H(7)O(2))(C(2)N(3))(C(12)H(8)N(2))]·2H(2)O, the Cu(II) atom is five-coordinated in a square-pyramidal geometry with two acetyl-acetonate O and two phenanthroline N atoms forming the base. The apical position is occupied by the central N atom of the dicyanamide ligand. The dicyanamide N atoms are each involved in hydrogen bonds to water mol-ecules. There are also hydrogen bonds between both the water mol-ecules and their centrosymmetric pairs, creating a hydrogen-bonded chain along the b-axis direction.

{?(2)-1,4-Bis[2-(4-pyrid-yl)ethen-yl]benzene-?N:N'}bis-[bis-(acetyl-acetonato-?O,O')copper(II)].

Project description:The asymmetric unit of the title compound, [Cu(2)(C(5)H(7)O(2))(4)(C(20)H(16)N(2))], contains half of a centrosymmetric dinuclear mol-ecule. In the mol-ecule, each Cu center is coordinated by four O atoms from two acetyl-acetonate ligands and one N atom from the bridging linear 1,4-bis-[2-(4-pyrid-yl)ethen-yl]benzene ligand in a square-pyramidal geometry. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into sheets parallel to the bc plane.

Redetermination of bis-(acetyl-acetonato-?(2) O,O')(1,10-phenanthroline-?(2) N,N')manganese(II).

Project description:In the crystal structure of the title compound, [Mn(C5H7O2)2(C12H8N2)], the Mn(2+) cation is coordinated by one bidentate 1,10-phenanthroline ligand and two acetyl-acetonate anions within a slightly distorted N2O4 octa-hedron. The asymmetric unit consists of one Mn(2+) cation situated on a twofold rotation axis, one half of a 1,10-phenanthroline ligand and one acetyl-acetonate anion. In comparison with the previous determination based on visually estimated intensities recorded on precession photographs, the current redetermination with image-plate data reveals bond lengths and angles with much higher precision.
