摘要
合成了二苯甲酰甲烷与N,N-二甲基丙二胺混配配合物Zn(dmapa)(dbm)2(1)和Cd(dmapa)(dbm)2(2)。用元素分析、红外光谱对配合物进行了表征,并用X-射线单晶衍射测定了配合物的晶体结构。配合物1属单斜晶系,P21/n空间群;配合物2属三斜晶系,Pī空间群。中心金属离子(Zn、Cd)与来自2个dbm-配体的4个O原子和来自dmapa配体的2个N原子配位,形成变型的八面体构型。研究了2个配合物的热稳定性。
Two complexes Zn (dmapa)(dbm)2(1) and Cd(dmapa)(dbm)2(2)(dmapa=3-dimenthylaminopropylamine, Hdbm=dibenzoylmethane) were synthesized and characterized by elemental analysis, IR, TGA and X-ray single crystal structure analysis. Complex 1 is of monoclinic, space group P21/n with a= 1.142 0(2) nm, b = 1.6230(3) nm, c = 1.744 8(4) nm,β=99.31(3)°, V=3.192(1)nm^3 and Z=4. Complex 2 is of triclinic, space group P^-1 with a= 1.174 (2) nm, b=1.2385(3) nm, c=1.3273(3) nm, α=66.85(3)°, β=86.96(3)°, γ=62.71(3)°, V=1.5584(6) nm^3, Z=2. Both complexes are mononuclear complexes with the metal center Zn(Ⅱ) or Cd(Ⅱ) coordinated by four O atoms from two dbm^- ligands and two N atoms from one dmapa ligand, adopting distorted octahedral coordination geometries.
