摘要

A new mixed-valence hexadecavanadate cluster compound, (Me2NH2)4[H6V_(16)O_(42)(SO4)]·8H2O (1), has been synthesized via an efficient method in organic media. The hollow cluster shell of 1, with a sulfate ion locating in its centre, exhibits four large eight-membered -O-V-O-V- rings on its surface, which makes the cluster into a half-open structure distinguished from the common hollow clusters built up with closed surfaces. The intense blue luminescence of 1 in solution state is scarcely reported for the polyoxometaiate clusters.
