3D supramolecular network constructed by intermolecular interactions in mixed ligand complex of zinc

3D supramolecular structure in the crystal of [Zn(quin-2-c)2(Him)2] is made by intermolecular interactions: N-H⋯O and C-H⋯O hydrogen bonds as well as the C-H⋯π and π⋯π type interactions. The vibrations of monodentate carboxylate group are severely influenced by strong hydrogen bond.
