Abstract
The reaction of diphenylphosphinic acid, [Ph2P(O)(OH)], with CoCl2 or ZnCl2 and 3,5-dimethylpyrazole (DMPZ) in the presence of triethylamine affords the mononuclear phosphinates, M(Ph2PO2)2(DMPZ)2 (M= Co(1), Zn(2)). The molecular structures of 1 and 2 reveal a tetrahedral environment around the metal. The phosphinate ligands are monoanionic and bind to the metal in a monodentate manner, while the pyrazole ligands act as neutral monodentate ligands. Intermolecular C-H-O and p-p interactions in 1 and 2 result in the generation of two dimensional supramolecular polymeric sheets in the solid state.
