By reaction of [ ω -diphenylphosphinoalkyl]diphenylphosphine sulphides Ph 2 P(CH 2 ) n P(S)Ph 2 ( n = 2–4) (L 1 −L 3 ) with AgNO 3 in CH 3 CN crystalline complexes with the composition metal:ligand 1:1 [Ag(L 1 )NO 3 , Ag(L 2 )NO 3 , Ag(L 3 )NO 3 ] and 1:2 [Ag(L 1 ) 2 NO 3 , Ag(L 3 ) 2 NO 3 ] were isolated. According to the X-ray analysis data, the crystals of Ag(L 1 )NO 3 are constructed from centrosymmetric dimeric molecules based on the 12-membered macrocycle AgSPCH 2 CH 2 PAgSPCH 2 CH 2 P ¯ . Each of the neutral ligands L 1 is a bridge between two silver ions and each of the silver ions is coordinated by a chelating NO 3 group. According to the IR spectra, the other 1:1 complexes also have an analogous structure. In the 1:2 complexes the coordinated NO 3 groups of the 1:1 complexes are replaced by the phosphine sulphide ligand. The downfield shifts of the signals of P III and P V atoms in 31 P NMR spectra of 1:2 complexes in comparison with the free ligands L 1 and L 3 reflect a participation of the P III atom and P=S group in complex formation. |
