catena-Poly[[[bis[diaqua(4,4'-bipyridine)cadmium(II)]-bis[mu-(N"-carboxymethyldiethylenetriamine-N,N,N',N"-tetraacetato)cadmium(II)]]-mu-4,4'-bipyridine] tetradecahydrate], [Cd-4 (C14H19N3O10)(2) (C10H8N2)(3) (H2O)(4)] . 14H(2)O or [Cd-4 (HDTPA)(2) (BPY)(3) (H2O)(4)] . 14H(2)O, where BPY is 4,4'-bipyridine and HDTPA(4-) is N"-carboxymethyldiethylenetriamine-N,N,N',N"-tetraacetate, consists of a one-dimensional coordination polymer formed from a secondary building unit which comprises four Cd centres. The chain structure of the title compound was obtained by the use of a multidentate organic ligand, N,N,N',N",N"-diethylenetriaminepentaacetic acid (H(5)DTPA), which forms multiple chelate rings with the Cd metal centres. An extended network is formed via hydrogen bonds.
