摘要：

X-ray structure analysis has confirmed the presence of the [Mo8O26]4- anion in [NH2(CH3)2]2-[N(C4H9)4]2[Mo8O26]: monoclinic, P2(1)/c, M(r) = 1760.63, a = 10.287 (2), b = 14.033 (4), c = 21.241 (4) angstrom, beta = 99.24 (2)-degrees, V = 3026.4 angstrom3, Z = 2, D(x) = 1.93 g cm-3, lambda(Mo Kalpha) = 0.7107 angstrom, mu = 16.4 cm-1, F(000) = 1752, T = 294 (1) K, R = 0.044, wR = 0.069 for 5137 observed reflections. Eight MoO6 distorted octahedra share edges with short terminal Mo-O bonds (1.694-1.741 angstrom), bonds of intermediate length (1.889-2.001 angstrom) and long bonds (2.165-2.465 angstrom). The structure contains the beta-Mo8O26 polyanion.
