AbstractTwo new complexes, [Ni(pydc)(H2O)3] (1) and [Ni(cma)(H2O)3] (2) (H2pydc = pyridine-2,6-dicarboxylic acid, H2cma = 2-(carboxymethoxy)benzoic acid), have been synthesized and structurally characterized. In both compounds, NiIIis surrounded by one tridentate chelate dianionic ligand (pydc2ˉ for1and cma2ˉ for2) and three coordinated water molecules in a distorted octahedral geometry (NiNO5for1and NiO6for2). The magnetic properties for1and2have been discussed in detail.
摘要合成并结构表征了两个新的配合物,[Ni(pydc)(H2O)3] (1) 和 [Ni(cma)(H2O)3] (2) (H2pydc = 吡啶-2,6-二甲酸,H2cma = 2-(羧甲氧基)苯甲酸)。在这两个化合物中,NiII被一个三齿螯合二阴离子配体(pydc2ˉ 对于1和cma2ˉ 对于2)和三个配位水分子所包围,呈扭曲的八面体几何结构(NiNO5对于1和NiO6对于2)。详细讨论了1和2的磁性质。
