报道邻香草醛缩乙醇胺与氯化镉形成的配合物的合成,并对其进行了元素分析,IR等项表征,对配体与氯化镉形成的配合物进行了激光倍频效应的测试和X射线单晶结构分析.[CdC_(20)H_(26)N_2O_6Cl_2]·(1/2)C_2H_6O,M_r=596.76,单斜晶系,空间群:C_c,a=1.5475(3),b=1.1661(2),c=1.7295(3)nm,β=116.50(3)°,Z=4.用直接法解得结构.R=0.043,R_w=0.052.结构分析表明,镉分别与两个配体中的四个氧原子及两个氯阴离子配位形成畸变的八面体构型,这种不对称结构导致了该配合物晶体具有非线性光学性能.

The tide complex [Cd(CH3OC6H3OHCH = NC2H4OH)2Cl2]·(1/2)C2H5OH was synthesized and characterized by elemental analyses, IR as well as UV spectroscopy. Its structure was confimed by single crystal X-ray diffraction. The complex crystal belongs to the monocline space group is Cc, with cell parameters: a = 1.5475(3), 6 = 1.1661(2), c = 1.7295 (3)nm, β= 116.50(3)°, Z = 4, final R= 0.043 for 2261 unique reflections [I≥3σ(I)]. The structure was solved by direct method. The results indicate that each of the cadmium atoms was coordinated with four oxygen atoms (from two ligands respectively), and two chlorine anions to form a twisted octahedron. The complex has a high SHG efficiency.
