catena-Poly[[[bis[diaqua(4,4′-bipyridine)cadmium(II)]-bis[μ -(N″-carboxymethyldiethylenetriamine-N,N,N′, N″-tetraacetato) cadmium(II)]]-μ-4,4′-bipyridine] tetradecahydrate], [Cd4(C14H19N3 O10)2(C10 H8N2)3 (H2O)4]· 14H2O or [Cd4(HDTPA)2(BPY)3 (H2O)4]·14H2O, where BPY is 4, 4′bipyridine and HDTPA4- 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 (H5DTPA), which forms multiple chelate rings with the Cd metal centres. An extended network is formed via hydrogen bonds.
