Abstract
Cyclohexaphosphoric acid (P6O18H6) reacts with cadmium carbonate and 4-chlorobenzylamine (CBA) to give the mononuclear title complex, (C7H9ClN)4[Cd(P6O18)]n, in which the CdII atom, lying on an inversion centre, has an octahedral coordination built of six O atoms of two centrosymmetric P6O18 rings. Each P6O18 ligand acts as a bridge, linking two CdII atoms and forming an anionic coordination polymer [Cd(P6O18)4−]n extending along [010]. Adjacent polymeric chains are connected through N—H⋯O and C—H⋯O hydrogen bonds, generating a three-dimensional supramolecular network.
