Abstract: Treatment of H3pdc with Zn(NO3)2·6H2O under different reaction conditions afforded two complexes,[Zn(H2pdc)2(H2O)2]·2H2O (1) and[Zn2(Hpdc)2(H2O)6]·2H2O (2) (H3pdc=3,4-pyrazoledicarboxylic acid). X-ray diffraction analyses reveal that 1 and 2 contain mono-and dinuclear Zn(Ⅱ) components, respectively. The partly deprotonated H3pdc ligand anions in 1 and 2 adopt N,O-chelating fashion (H2pdc-) and μ2-κN,O:κN' bridging mode (Hpdc2-), respectively. In both complexes, the adjacent zero-dimensional components are connected by intermolecular hydrogen bonds (O-H…O, N-H…O and C-H…O) to form a three-dimensional supramolecular architecture. The thermal and luminescent properties of complexes 1 and 2 have also been investigated.
