COMPLEXATION OF (CARBAMOYLMETHYL)DIPHENYLPHOSPHINE SULFIDE WITH SILVER-NITRATE - THE STRUCTURE OF THE POLYMERIC COMPLEX [AG-2(PH2P(S)CH2C(O)NH2)(2)(NO3)(2)](N)

The reaction of (carbamoylmethyl)diphenylphosphine sulfide with AgNO3 yields the polymeric complex [Ag-2(Ph2P(S)CH2C(O)NH2}(2)(NO3)(2)](n). Its structure was established by X-ray diffraction analysis. The coord ination environments about both Ag+ cations are formed by five donor a toms, two of which are bonded to the metal atom substantially more wea kly than the remaining three atoms. The compositions of the coordinati on polyhedra are different: ({AgSO'(C)O(N)O-2(N')} and (AgS'SO(C)O-2(N )}). The coordinated ligands differ in their functions: one ligand che lates the metal cation and its sulfur atom is additionally bonded to t he 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 aff ected by the network of hydrogen bonds.
