摘要
在室温下,由过渡金属醋酸盐与香兰素(HL,C8H8O3)直接进行一步固相反应合成了5种配合物[ML2(H2O)2](M=Mn,Co,Ni,Cu,Zn)1-5,用XRD、元素分析、摩尔电导、红外光谱、热分析方法进行表征.中心金属离子M(II)与2个香兰素基中的酚羟基氧和甲氧基氧的4个氧原子以及2个水分子中的2个氧原子发生配位,形成分子配合物,配位数为6.
Five solid complexes 1-5 with the stoichiometric formulae [ML2 ( H2O ) 2 ] ( M = Mn, Co, Ni, Cu, Zn ) have been synthesized by one--step solid state reacting transition matal acetate with vanillin ( HL, C8H8O3 ) at room temperature, and characterized by XRD, elemental anlysis, molar conductance, IR spectra, TG-DTG. Every central M ( Ⅱ ) ion in the complexes coordinates with four oxygen atoms of the two vanillin of phenolic hydroxy oxygen atom and methoxy atom and two oxygen atoms of two coordination water molecular. Their coordination numbers are six.
