| Abstract: The title compound was prepared by two methods. The crystal belongs to space group Pnma with a= 12.043(1), b= 11.521(1), c= 14.137(2)Å, V=1961.6Å3, Z = 4, Dc=3.35g·cm-3, M = 989.47, F(000)= 1776, n= 194.06cm-1. The structure was refined to a final R = 0.064 for 1266 observed reflections. The cluster anion has a W3OC13 core, which shows an apexdeficient quasicubane configuration. The IR absorption bands in the cluster were assigned. |
