用一步法合成了一个Schiff碱配合物[Cd(H2SalN)2(OAc)2(H2O)].3(H2O)(H2SalN=salicylalde-hyde isonicotinoylhydrazone),并用IR和X射线单晶衍射进行了结构测定.该化合物属于三斜晶系,P-1空间群,晶胞参数为:a=1.554 4(3)nm,b=1.556 9(3)nm,c=1.716 3(3)nm,α=66.972(3)°,β=64.634(3)°,γ=81.289(3)°,Z=4,Dc=1.545g/cm3,μ=0.705mm-1,F(000)=1 648,R1=0.075 2,wR2=0.191 4.在配合物中,中心金属离子镉(Ⅱ)与五个氧原子(来自两个羧基和一个水分子),两个氮原子(来自两个H2SalN配体)形成七配位构型.在分子内及分子间有氢键连接,形成三维扩展结构.
A one-step synthesis of a Schiff base complex [Cd (H2SalN) 2 (OAc) 2 (H2O)] .3 (H2O) (H2SalN = salicylalde-hyde isonicotinoylhydrazone) was also investigated by IR and X-ray single crystal diffraction . The compound belongs to the triclinic system with P-1 space group with unit cell parameters of a = 1.554 4 (3) nm, b = 1.556 9 (3) nm, c = 1.716 3 (3) °, β = 64.634 (3) °, γ = 81.289 (3) °, Z = 4, Dc = 1.545g / cm3, μ = 0.705mm-1, F 2, wR2 = 0.191 4. In the complex, the central metal ion, cadmium (II), forms seven complexes with five oxygen atoms (from two carboxyl groups and one water molecule) and two nitrogen atoms (from two H2SalN ligands) In the intramolecular and intermolecular hydrogen bonding, a three-dimensional extended structure is formed.
