THE COMPLEXATION OF (N,N-DIETHYLCARBAMOYLMETHYL)DIPHENYLPHOSPHINE SULFIDE WITH SILVER-NITRATE

The crystalline complex [Ag(L(1))NO3](2) (A) was isolated by the inter action of (N,N-diethylcarbamoylmethyl)diphenylphosphine sulfide Ph(2)P (S)CH2(C)(O)NEt(2) (L(1)) with AgNO3 in different solvents at the rati os of metal:ligand = 1:1 and 1:2. According to the X-ray data, complex A is a center-symmetric dimer with bridge sulfur atoms. The cations o f the metal are in a tetrahedral environment formed by two S atoms and the O atoms of CO and NO3 groups. The interaction of L(1) with AgNO3 was studied in solution by IR spectroscopy, and the structures of the complexes formed are discussed.
