Description
Summary:In the title polymeric coordination complex, {[Cd(C22H20N2O6)(H2O)4](NO3)2·0.5H2O}n, obtained from the self-assembly of the flexible double betaine 3,3′-[p-phenylenebis(oxymethylene)]bis(1-pyridinioacetate) with cadmium nitrate, both the octahedrally coordinated CdII cation and the substituted betaine ligand lie on inversion centres. The chains constructed through the trans-related acetate groups of the ligand are inter-connected via O—H...O hydrogen bonds involving coordinated aqua ligands, the nitrate anions and the partial-occupancy (0.25) water molecule of solvation, forming a three-dimensional structure.
