abstract
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.
