| Abstract: | Two coordination polymers Zn(L)2(4,4′-bipy)2] n (4,4′-bipy = 4,4′-bipyridine) (1) and Pb(η 2-L)(µ3-η 2-CH3COO)(H2O)] n (2) have been prepared by the reaction of 3-(4-carboxyphenylhydrazono)pentane-2,4-diketone (HL) with zinc(II) or lead(II) in solution. Polymer 1 shows an infinite zigzag chain, in which Zn(II) are linked by 4,4′-bipy bridges with carboxylate of L? monodentate to Zn(II). In 2, Pb(II) are bridged by tetradentate µ3-η 2-CH3COO? to form a linear 1-D chain, and each Pb(II) is chelated by carboxylate of L?. Their molecular structures have been characterized by elemental analysis, infrared, and single-crystal X-ray diffraction. Thermal and fluorescent properties of the two complexes have been investigated. |
