Abstract
The 1 : 1 and 1 : 2 complexes of AgNO3 with Ph2PCH2P(O)Ph2 were prepared and their structures were established by IR and 31P NMR spectroscopy and X-ray diffraction analysis. The crystal of the 1 : 1 complex consists of centrosymmetric dimers based on the ten-membered macrocycle AgOPCH2PAgOPCH2P. Each neutral ligand serves as a bridge between two silver ions, the latter being coordinated by the NO3 group in the monodentate fashion. In the 1 : 2 complex, the dimeric structure is retained, but both NO3 groups are replaced by the ligand molecules.
