The crystal structure of [(2,2′-bipyridine-k2N,N)-bis(6-phenylpyridine-2-carboxylate-k2N,O)copper(II)], C34H24N4O4Cu.

The Cu(II) ion locates in a distorted octahedral geometry, defined by one O atom (O2) form one 6-phenylpyridine-2-carboxylate ligand and one N atom (N1) from 2,2'-bipyridine ligand at the axial positions (O2-Cu1-N1, 173.37(6)°), one O atom (O2') and two N atoms (N2, N2') form 6-phenylpyridine-2-carboxylate ligand, and one N atom (N1') from the 2,2'-bipyridine ligand in the equatorial plane. 8 Liu, S.-Y., Tian, J.-J., Zhu, L.-J., Tian, H.-T., Yang, M., Huang, K.-L., Xu, W.-T. 13 Wang, L.-H., Wang, Z.-J., Ouyang, J., Tai, X.-S.
