In the crystal structure of the title compound, K(4)[Au(4)Ni(2)(C(6)H(8)NO(4)S)(C(5)H(9)NO(2)S)(4)(C(5)H(10)NO(2)S)].C(2)H(6)O.10H(2)O, (I), two planar Ni(C(5)H(9)NO(2)S)(2) units are spanned by Au(2)(C(5)H(10)NO(2)S) and Au(2)(C(6)H(8)NO(4)S) linkers through S atoms, forming an S:S-bridged Au(I)(4)Ni(II)(2) hexanuclear complex anion. One of six organic ligands in the complex anion is a carbamino derivative of D-penicillamine (3-mercaptovaline) and the others are deprotonated D-penicillamines. Each complex anion binds to nine K(+) ions through six carboxylate and one carbamino groups to construct a three-dimensional structure.
在标题化合物K(4)[Au(4)Ni(2)(C(6)H(8)NO(4)S)(C(5)H(9)NO(2)S)(4)(C(5)H(10)NO(2)S)].C(2)H(6)O.10H(2)O(I)的晶体结构中,两个平面Ni(C(5)H(9)NO(2)S)(2)单元通过硫原子由Au(2)(C(5)H(10)NO(2)S)和Au(2)(C(6)H(8)NO(4)S)连接体桥连,形成一个S:S桥连的Au(I)(4)Ni(II)(2)六核复合阴离子。复合阴离子中的六个有机配体之一是D-青霉胺(3-巯基缬氨酸)的氨基甲酰衍生物,其他的是去质子化的D-青霉胺。每个复合阴离子通过六个羧酸根和一个氨基甲酰基与九个K(+)离子结合,构建出一个三维结构。
