Bis(2,2′-bipyridine)(2-hydroxy-2,2-diphenylacetato)copper(II) nitrate dihydrate

Abstract

In the title complex, [Cu(C14H11O3)(C10H8N2)2]NO3·2H2O, the CuII atom is coordinated by four N atoms from two 2,2′-bipyridine ligands and two O atoms from one benzilate ligand in a distorted octahedral geometry. A supramolecular network is formed via intermolecular O—H...O and C—H...O hydrogen-bonding interactions. π–π stacking interactions between neighboring pyridine rings are also present, the centroid—centroid distance being 3.808 (2) Å.
