Synthesis and Characterization of a Bismuth Incorporating Heptamolybdate: (NH4)(4)[HMo7O24Bi(H2O)(2)C5H3N(CO2)(2)]center dot 7H(2)O

A new one-dimensional molecule based on the linkage of [Mo7O24] clusters and [BiL] (L = pyridine-2,6-dicarboxylic acid) assembles under ambient conditions. The title compound was characterized by X-ray powder diffraction, IR and UV spectra, thermogravimetric analysis, and single-crystal X-ray diffraction. Crystal data: C7H38BiMo7N5O37, M-r = 1664.95, monoclinic, space group C2/c, a = 24.312(2), b = 21.4869(18), c = 18.5423(16) angstrom, beta = 111.6490(10)degrees, V = 9002.9(13) angstrom(3), Z = 8, mu = 5.883 mm(-1), F(000) = 6304, GOF = 1.045, R = 0.0365 and wR = 0.1062.
