Three new coordination compounds have been prepared by reacting copper salts with sulfonamides derived from amino acids. Their molecular structures have been determined with the aid of single crystal X-ray diffraction. The copper cations are four-coordinated in all cases and the local environment is almost planar. Compound [Cu(ts-gly)(NH3)2]·H2O (1) crystallizes in monoclinic space group P21/c (no
通过铜盐与氨基酸衍生的磺胺反应制备了三种新的配位化合物。它们的分子结构已在单晶 X 射线衍射的帮助下确定。铜阳离子在所有情况下都是四配位的,局部环境几乎是平面的。化合物 [Cu (ts-gly) (NH3) 2] · H2O (1) 在单斜晶系 P21 / c (no 14) 中结晶,Z = 4,晶胞参数 a = 6.0490 (12) A, b = 24.719 (5) A, c = 9.159 (2) A, α = γ = 90°, β = 94.69 (3)°。化合物 [Cu (ts-isoleu) (NH3) 2] (2) 在单斜空间群 C2 / c (no 8) 中结晶,Z = 15,晶胞参数 a = 30.800 (6) A, b = 6.5510 (13 ) A, c = 15.830 (3) A, α = γ = 90 °, β = 100.19 (3) °。化合物 Na
