Single crystals of [Cd(terephthalate) (H2O)(3)].4H(2)O (1), triaquo(1,4-benzenecarboxylato-kappa O)cadmium tetrahydrate, are grown in a silica gel column. Crystal structure analysis shows that (1) is a polymer with metal-organic chains stacked along the a axis forming layers parallel to the ab plane. These layers are linked by an unusual hydrogen-bonded network formed by the water molecules (both 'free' and coordinated ones) and the carboxylate O atoms. This network comprises tridymite-like O-8 cages which 'propagate' in the direction of the a axis, mimicking the way they 'propagate' along the c axis in hexagonal ice.
