characterized by elemental analyses, 1H NMR, 13C NMR, UV/Vis, IR, and mass spectra. Spectroscopic evidences suggest a four-coordinate distorted square planar structure for 2. The molecular and crystal structure of 2 was determined by single crystal X-ray analysis. Crystallographic data for 2 at 291(2) K: space group C2/c, a = 20.340(3), b = 15.503(3), c = 7.659(1) A, β = 95.96(2)°, Z = 4, R1 = 0.044 and
S-烯丙基-β-N-(亚苄基)二硫代氨基甲酸酯 (sabdtc, 1),由水合肼、二硫化碳、烯丙基溴和苯甲醛制备,在乙醇溶液中与硝酸铜 (II) 反应形成复合物 Cu (sabdtc) 2 (2). 1 充当单个带负电荷的双齿螯合配体,并通过偶氮甲碱氮原子和硫烯化硫原子与金属离子配位。1和2通过元素分析、1H NMR、13C NMR、UV/Vis、IR和质谱表征。光谱证据表明2的四坐标扭曲方形平面结构。2的分子和晶体结构由单晶X射线分析确定。2 在 291 (2) K 处的晶体学数据:空间群 C2/c,a = 20.340 (3),b = 15.503 (3),c = 7.659 (1) A,β = 95.96 (2)°,Z = 4 , R1 = 0.044 和 wR2 = 0.0689。
