摘要：
Four new complexes {[Zn(HL)(H2O)(DMF)](NO3)}(n) (1), [Cd(HL)(2)](n) (2), {[Mn(HL)(2)]center dot CH3CN center dot 2H(2)O} (3) and {[Mn(L)(mu(2)-EtOH)]}(n) (4) (H2L = N-(1-phenyl-3-methyl-4-benzal-pyrazolone-5)-nicotinic hydrazide) have been synthesized and characterized by elemental analyses, IR spectra, thermal analyses and single crystal X-ray diffraction. The structural analyses reveal that complexes 1, 2 and 3, formed by H2L with metal nitrate, have Zigzag chain, double-stranded chain and mononuclear structures, respectively, and the ligands adopt three different coordination modes in these complexes. While, complex 4, formed by H2L with manganese acetate, represents a 2D network structure with dinuclear units bridged by ethanol molecules. These result demonstrated that the metal atom and counteranion have certain influences on the structures of resulting complexes. In addition, the fluorescent properties of 1 and 2 and the magnetism of 4 were investigated. (C) 2013 Elsevier Ltd. All rights reserved.
