Reactions of 4-diphenylphosphino benzoic acid with organotin oxides and -oxy-hydroxide

The reactions of p-diphenylphosphinobenzoic acid (LCOOH) with various organotin precursors have been carried out. Accordingly, the reaction of with LCOOH afforded the hexameric compound, — (1). On the other hand, the reaction of LCOOH with gave the tetrameric compound — (2). The 1-D coordination polymers —, (3), (4)] were prepared in the reaction of or with LCOOH. The compounds 1-4 were structurally characterized by multinuclear NMR spectroscopic and single crystal X-ray diffraction studies. SYNOPSIS The reactions of p-diphenylphosphinobenzoic acid with various organotin precursors have been shown to afford hexameric compound 1, tetrameric compound 2 and 1-D polymeric compounds 3 and 4. The compounds 1-4 were structurally characterized by multinuclear NMR spectroscopic and single crystal X-ray diffraction methods
