-hypophosphito-bis[(2,2'-bipyridine)copper(II)] nitrateAbstract: The structure of blue [Cu2(O2PH2)2(C10H8N2)2](NO3)2 consists of dimeric [Cu(O2PH2)(bipy)] subunits (bipy = 2,2'-bipyridine) joined by two hypophosphite bridging ligands, with each metal center in a distorted planar arrangement. These joined subunits exist as a discrete cation with the equivalent of two nitrates as counter-ions. The subunits have a four-coordinated distorted square-planar arrangement of N and O atoms from the 2,2'-bipyridine and hypophosphite ligands, with the fifth and sixth positions of the copper coordination occupied by neighboring O atoms of the nitrate counter-ions.
