Abstract: In the presence of different N ancillary ligands, treatment of H2MPCA with corresponding Pb(Ⅱ) salts afforded two complexes,[Pb(HMPCA)2(H2O)2]·H2O (1) and[Pb(HMPCA)2(phen)]·H2O (2) (H2MPCA=5-methyl-1H-pyrazole-3-carboxylic acid, phen=1,10-phenanthroline). In dinuclear complex 1, the[Pb(μ2-HMPCA))]2 units are extended into a 1D chain structure by a pair of Pb…O secondary bonds. Then, these 1D chains are further assembled to a 2D supramolecular structure through intermolecular hydrogen bonds. While complex 2 displays a mononuclear structure, the Pb…O secondary bonds emerged in the Pb2O2 rhomb, which are further packed into a 3D supramolecular framework though π…π interactions and hydrogen bonds. The thermal and luminescent properties of complexes 1 and 2 have also been investigated. |
