Bis[-bis(4-nitrophenyl) phosphato-²O:O]bis[(4,4'-dimethyl-2,2'-bipyridine)nitratocopper(II)]

J. R. Deschamps, C. M. Hartshorn and E. L. Chang

Abstract: The title dimeric complex, [Cu₂(L)₂(BNPP)₂(NO₃)₂], is formed between 4,4'-methyl-2,2'-bipyridine (L, C₁₂H₁₂N₂), copper(II), and the substrate BNPP [bis-(4-nitrophenyl)phosphate, C₁₂H₈N₂O₈P], with the two subunits, [Cu(L)(BNPP)NO₃)] related by a center of inversion. The coordination geometry about the Cu atoms is square pyramidal, with phosphate O atoms occupying both an in-plane and an out-of-plane sites. While the dimeric scheme is similar to other five-coordinate copper(II) complexes of bipyridine, the alternating in-plane and out-of-plane bridging of the copper(II) centers by BNPP is unusual.
