METAL BETAINE INTERACTIONS .11. STRUCTURE OF CATENA-[MU-DICHLORO-(TRIETHYLAMMONIOACETATO)CADMIUM(II)]

A new cadmium(II) complex of triethylammonioacetate [(C2H5)3N+ CH2COO-, designated Et3BET] has been prepared and characterized. [Cd{(C2H5)3NCH2COO}(mu-Cl)2]n, M(r) = 342.55, monoclinic, C2/c, a = 18.097 (4), b = 9.714 (2), c = 13.845 (1) angstrom, beta = 92.46 (1)-degrees, U = 2431.1 (7) angstrom 3, Z = 8, D(m) = 1.862, D(x) = 1.871 g cm-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 22.1 cm-1, F(000) = 1360, T = 298 (1) K. R = 0.024 for 2875 unique Mo K-alpha observed data. Each Cd(II) atom is in a distorted octahedral environment, surrounded by an uncommon symmetrical bidentate chelating carboxylato group and two pairs of bridging chloro ligands. Successive octahedra related by the c-glide share edges to generate a one-dimensional polymeric structure.
