Structure of hexaaquadichloroyttrium(III) chloride

[YC12(H20)6]C1, Mr = 303.356, monoclinic, P2/n, a = 7.8346 (25), b = 6.4729 (26), c = 9.5817 (50) angstroms, beta = 93.768 (35) °, V = 484.86 cubic angstroms, Z = 2, Dx = 2.0776 g cm -3, Mo Kalpha (A = 0.71069 angstroms),/z = 68.66 cm- 1, F(000) = 300, room temperature, final R = 0.0449 for 940 unique observed reflexions. The yttrium is coordinated, as expected, by two chlorines and six water molecules in a square antiprismatic arrangement.
