Complexation of (carbamoylmethyl)diphenylphosphine sulfide with silver nitrate. The structure of the polymeric complex [Ag2{Ph2P(S)CH2C(O)NH2}2(NO3)2] n

The reaction of (carbamoylmethyl)diphenylphosphine sulfide with AgNO₃ yields the polymeric complex [Ag₂{Ph₂P(S)CH₂C(O)NH₂}₂(NO₃)₂] _n . Its structure was established by X-ray diffraction analysis. The coordination environments about both Ag⁺ cations are formed by five donor atoms, two of which are bonded to the metal atom substantially more weakly than the remaining three atoms. The compositions of the coordination polyhedra are different: ({AgSO′(C)O(N)O₂(N′)} and {AgS′ SO(C)O₂(N)}). The coordinated ligands differ in their functions: one ligand chelates the metal cation and its sulfur atom is additionally bonded to the second cation, while the second ligand acts as a bridge between the two different cations. The structure of the complex and the character of the interaction between the ligand and AgNO₃ are substantially affected by the network of hydrogen bonds. Translated fromIzvestiya Akademii Nauk.
