Abstract. The title compounds NH4[Cu(S2CNH2)2]·H2O (A) and CuS2CNH2 (B) were prepared from aqueous alcoholic solutions by reaction of ammoniumdithiocarbamate with copper sulfate in presence of excess cyanide as reductive. (A) crystallizes in the orthorhombic space group C2221 (No. 20) with a = 8.9518(6), b = 9.6414(6) and c = 10.6176(8) A, Z = 4. (B) crystallizes in the orthorhombic space group P212121
摘要。标题化合物NH4[Cu(S2CNH2)2]·H2O(A)和CuS2CNH2(B)是通过二硫代氨基甲酸铵与硫酸铜在过量氰化物作为还原剂存在下反应,由含水醇溶液制备的。(A) 在正交空间群 C2221 (No. 20) 中结晶,a = 8.9518(6), b = 9.6414(6) 和 c = 10.6176(8) A, Z = 4. (B) 在正交空间中结晶P212121组(No. 19),a = 5.9533(4), b = 6.6276(4) and c = 9.4834(5) A, Z = 4。在(A)铜的晶体结构中,四面体周围有四个单齿二硫代氨基甲酸酯配体。这些结构单元形成沿[001]堆叠的二维网络。由 H2O 和 NH4+ 组成的交错链沿 [001] 穿透晶体结构,通过氢键产生额外的相干性。(B) 的晶体结构包括由顶点专门连接的 CuS4 单元的三维四面体框架。这种排列让人联想到填充的
