2-ethanediylbis(iminomethylene)bis(phosphonic acid) in acidic conditions yieldeddichloro[1,2-ethanediylbis(iminomethylene)bis(phosphona-to)]trizinc dihydrate, Zn3Cl2(HO3PCH2NHCH2CH2NHCH2-PO3H)2·2 H2O which crystallizes in the monoclinic system and space group P21/n, with the unit cell parameters a = 9.94316(4), b = 10.44577(5), c = 24.3240(1) A, β = 90.003(1)°, and Z = 4. The crystal structure was determined
氯化锌与1,2-乙二基双(亚氨基亚甲基)双(膦酸)在酸性条件下反应生成二氯[1,2-乙二基双(亚氨基亚甲基)双(膦酰基-to)]三锌二水合物,Zn3Cl2(HO3PCH2NHCH2CH2NHCH2-PO3H)2· 2 H2O 在单斜晶系和空间群 P21/n 中结晶,晶胞参数 a = 9.94316(4), b = 10.44577(5), c = 24.3240(1) A, β = 90.003(1)°,并且Z = 4。使用程序EXPO 和GSAS 从其粉末图案从头开始确定晶体结构。锌原子处于四面体环境中并与膦酸酯基团形成 16 元环。该结构与相应的 Cd 配合物的结构明显不同,因为 Cd 是六重配位的,并且配体与金属的比例不同。(© Wiley-VCH Verlag GmbH & Co.
