The title compound crystallyzes in the triclinic space grup P1 with four formula units in a cell of dimensions a = 22.199(11), b = 15.357(6), c = 10.223(4) A, alfa = 103,78(3), beta = 83.06(4) and gamma = 88.89(4). The structure was solved by the heavy-atom method and refined by least-squares calculations to R = 0.095 for 3473 counter data. It consists of two crystallographically independent, but chemically equivalent Cu(bglyO)2(bipy)(PrOH) molecules, which are linked in dimeric units by hydrogen bonding interactions. Each Cu atom shows a slightly distorted square-pyramidal five co-ordination by the bidentate 2,2'-bipyridine ligand and two N-benzyloxycarbonylglycinate ions in the equatorial plane, and by the propan-2-ol molecule in an apical position. The crystal packing is mainly determined by the intermolecular stacking and hydrophobic interactions between the 2,2'-bipyridine molecules and between phenyl groups, respectively. Its pohysical properties are also discussed in the light of its known crystal structure.
