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.
