?-Oxalato-bis-[bis-(2,2'-bipyridine)-manganese(II)] bis(perchlorate) 2,2'-bipyridine solvate.

ABSTRACT: The unit cell of the title compound, [Mn(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·C(10)H(8)N(2), consists of a binuclear cation, two perchlor-ate anions, and one solvent 2,2'-bipyridine (bpy) mol-ecule. In the complex cation [Mn(2)(C(2)O(4))(C(10)N(2)H(8))(4)](2+), two Mn(II) atoms are bridged by a bis-(bidentate) oxalate ligand, each Mn(II) atom being further coordinated by two bpy ligands in a distorted octa-hedral geometry. The distance between the two six-coordinated metal atoms is 5.583?(1)?Å. ?-? stacking inter-actions [inter-planar distances between bpy rings = 3.739?(1)?Å] are essential to the supramolecular assembly. There are extensive inter-ionic C-H?O inter-actions between the cations and between the cation and anion. Three of the four perchlorate O atoms are disordered over two sets of sites with occupancy ratios of 0.852?(6):0.148?(6).

μ-Oxalato-bis-[(2,2'-bipyridyl)-copper(II)] bis(perchlorate) dimethyl-formamide disolvate monohydrate.

Project description:The title compound, [Cu(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·2C(3)H(7)NO·H(2)O, contains doubly charged centrosymmetric dinuclear oxalato-bridged copper(II) complex cations, perchlorate anions, and DMF and water solvate mol-ecules. In the complex cation, the oxalate ligand is coordinated in a bis-bidentate bridging mode to the Cu atoms. Each Cu atom has a distorted tetra-gonal-bipyramidal environment, being coordinated by two N atoms of the two chelating bipy ligands and two O atoms of the doubly deprotonated oxalate anion. Pairs of perchlorate anions and water mol-ecules are linked into recta-ngles by O-H⋯O bonds in which the perchlorate O atoms act as acceptors and the water mol-ecules as donors. Methyl groups of the DMF solvent molecule are disordered over two sites with occupancies of 0.453 (7):0.547 (7), and the water molecule is half-occupied.
