Abstract
The anions of the title compounds contain [Ag(SCN)(4)] units, with the S at oms coordinating to Ag+ in a tetrahedral arrangement. Whereas in the isolat ed anions of tripotassium tetrathiocyanatoargentate(I), K-3[Ag(SCN)(4)], (I ), all SCN- groups are bonded as terminal ligands, in tetrapotassium di-mu -thiocyanato-S:S-bis[dithiocyanatoargentate(I)], K-4[Ag-2 (SCN)(6)], (II), two AgS4 tetrahedra share one common edge. In poly[potassium [argentate(I)- di-mu -thiocyanato-S:S]], K[Ag(SCN)(2)], (III), edge- and vertex-sharing of AgS4 tetrahedra results in infinite [Ag(SCN)(2)](-) layers.
