title: (2,2'-Bipyridine-kappa2N,N')(dichromato-kappaO)copper(II).
abstract: The title compound, [Cu(Cr(2)O(7))(C(10)H(8)N(2))(2)], a new mixed-metal molecular compound, contains isolated molecular units, each comprised of one Cu(II) atom coordinated to two 2,2'-bipyridine ligands and also to an oxygen vertex of a dichromate anion. The Cu(II) atom has an approximate trigonal-bipyramidal geometry, which is consistent with previous studies. Both enantiomers of the chiral complex molecule are present and are related by inversion centers. In a reported pyridine analogue, achiral [Cu(Cr(2)O(7))(pyridine)(4)] chains pack in the non-centrosymmetric space group Pna2(1). Differences in the organic ligands influence the chirality and dimensionality of the Cu-Cr(2)O(7) bonding.
