(2,2′-bipyridine-κ²N,N′)(dichromato-κO)copper(II)

The title compound, [Cu(Cr₂O₇)(C₁₀H₈N₂)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(Cr₂O₇)(pyridine)₄] chains pack in the non-centrosymmetric space group Pna2₁. Differences in the organic ligands influence the chirality and dimensionality of the Cu-Cr₂O₇ bonding.
