Isostructural organic-inorganic hybrids of P,P '-diphenyl-methylenediphosphinate (CH2(P(Ph)O-2)(2))(2-) with divalent transition metals

New organic-inorganic hybrid materials have been synthesized by reaction in water solution of manganese, cobalt or nickel acetates with P, P'-diphenylmethylenediphosphinic acid and all the two-dimensional structure coordination polymers obtained have been found to be isomorphous.
