A two-dimensional cadmium(II)-iminodiacetate polymer

B.-X. Liu and D.-J. Xu

Abstract: The title compound, poly[[aquatri-₃-iminodiacetato-tricadmium(II)] trihydrate], {[Cd₃(C₄H₅NO₄)₃(H₂O)]·3H₂O}_n, consists of a polymeric Cd^II-iminodiacetate network and uncoordinated water molecules. One Cd atom located on a general position is surrounded by three iminodiacetate (IDA) dianions, while a second Cd atom located on a mirror plane is coordinated by three IDA dianions and one water molecule. Both Cd^II atoms possess distorted octahedral coordination geometries. The iminodiacetate dianion bridges neighbouring Cd^II atoms to form polymeric sheets.
