Synthesis and characterization of two new cadmium phosphonocarboxylates Cd 2 (OH)(O 3 PC 2 H 4 CO 2 ) and Cd 3 (O 3 PC 2 H 4 CO 2 ) 2 ·2H 2 O Academic Article uri icon


  • The coordination chemistry of 2-carboxyethylphosphonic acid with cadmium salts is described, leading to two new pillared layered phosphonates that were fully characterized using 31P and 113Cd solid state NMR spectroscopy. A densely packed arrangement is observed for Cd2(OH)(O3PC2H4CO2), exhibiting structural features uncommon in metal phosphonates: a triply bridging OH, a (222) connectivity for the PO3 groups and a mixed 5-fold and 6-fold coordination for the metal.
