摘　　要：以2-(N,N-二(2-吡啶甲基)氨甲基)-6-醛基-4-甲基苯酚(HL)为配体合成了一个新的双核钙配合物[Ca2L2(NO3)2](1)和一个单核镉配合物[Cd(HL)(NO3)2](2),在碱性条件下,2能转化为双核镉配合物[Cd2L2(NO3)2]·H2O(3)。分别对它们进行了红外、质谱、元素分析和单晶结构表征。配合物1和3属于单斜晶系,空间群分别为P21/c和C2/c,配合物2属于三斜晶系,空间群为P1。单晶结构表明,配合物1含有一个酚氧桥连的双核钙单元[Ca2O2],每个钙均为八配位的扭曲十二面体构型[CaN3O5],配位原子分别来自一个配体L-的3个氮原子和一个酚氧原子、另一个配体L-的一个酚氧原子和一个醛氧原子以及一个硝酸根的2个氧原子。2是一个单核镉配合物,八配位镉的配位构型是扭曲的十二面体[CdN3O5],配位原子分别来自配体HL的3个氮原子和一个酚氧原子以及2个硝酸根的4个氧原子,醛基不参与配位。配合物3含有一个酚氧桥连的双核镉单元[Cd2O2],每个镉均为七配位的单帽三棱柱构型[CdN3O4],配位原子分别来自一个配体L-的3个氮原子和一个酚氧原子、另一个配体L-的一个酚氧原子和一个醛氧原子以及一个硝酸根的一个氧原子。A novel binuclear calcium complex [Ca2L2(NO3)2](1) and a mononuclear cadmium complex [Cd(HL)(NO3)2](2) have been successfully synthesized by using 2-(N,N-di(2-pyridylmethyl)aminomethyl)-6-aldehydo-4-methylphenol (HL) as a ligand. Complex 2 can be transformed to a binuclear cadmium complex [Cd2L2(NO3)2]·H2O (3) under basic conditions. Complexes 1~3 have been characterized by FT-IR, ESI-MS, elemental analysis and single-crystal X-ray diffraction. Both 1 and 3 crystallize in monoclinic system, but with space group P21/c and C2/c, respectively, while 2 in triclinic system with space group P1. X-ray crystallography analysis reveals that 1 has a bi-calcium unit [Ca2O2] bridged by two phenolato O atoms, and each eight-coordinated Ca(Ⅱ) cation shows a distorted dodecahedron configuration [CaN3O5] with three N atoms and one phenolato O atom from one L-, one phenolato O atom and an aldehyde O atom from another L- ligand, and two O atoms from one nitrate. 2 is a mononuclear cadmium complex and Cd(Ⅱ) cation is eight-coordinated by three N atoms and one phenol O atom from HL ligand and four O atoms from two nitrates to show a distorted dodecahedron configuration [CdN3O5],whereas the aldehyde group does not take part in coordination. 3 contains a bi-cadmium unit [Cd2O2] bridged by two phenolato O atoms, and each seven-coordinated Cd(Ⅱ) cation shows a distorted monocapped trigonal prism configuration [CdN3O4] with three N atoms and one phenolato O atom from one L-, one phenolato O atom and an aldehyde O atom from another L- ligand, and one O atom from one nitrate.
