چکیده
In the mol-ecule of the title compound, C(16)H(18)N(4)O(4), the dihedral angle between the mean planes of the two benzene rings is 56.76 (5)°. The crystal structure reveals extensive inter-molecular hydrogen bonds between carbonyl O atoms and primary amines, as well as between primary and secondary amines of hydrazide, forming rings of R(2) (2)(10) and R(2) (2)(6) motifs, respectively. The structure is further stabilized by intra-molecular and non-classical hydrogen bonds of the types N-H⋯O and C-H⋯O, respectively. The structure does not show any π-π inter-actions.

The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], was obtained by solvothermal synthesis. The Cu(II) atom is coordinated by one chelating 2,2'-bipyridine ligand and two carboxyl groups from different biphenyl-2,2'-dicarboxyl-ate ligands, leading to a distorted octahedral environment. Each carboxyl-ate group makes one short Cu-O bond [1.9608 (14) and 1.9701 (14) Å] and one longer ...
