| Abstract: | Chelate-like Sandwich Complexes of the Tripod Ligand Tris(diethoxyphosphoryl)phosphane with Bivalent Cations of Manganese, Iron, Cobalt, and Nickel PP(O)(OR)2]3 ( 1 , R ? C2H5) and the transition metal hexafluoroarsenates M(SO2)2(AsF6)2 (M ? Mn, Fe, Co, Ni) form the remarkably stable 2:1 complexes M{PP(O)(OR)2]3}2 (AsF6)2 2–5 in liquid SO2. Two tripod chelate ligands are arranged like a sandwich around the metal cation. Spectroscopic and magnetic properties of the compounds are discussed. |
