摘要：

A novel compound [（NH4）6][Gd2Mo36O112（H2O）20]·52H2O （1） was obtained from the reaction of （NH4）6Mo7O24·4H2O with GdCl3 at pH = 1.32. The X-ray structural analysis reveals that 1 crystallizes in monoclinic system, space group C2/c, Mr = 6937.77, a = 42.313（1）, b=12.924（1）, c=26.404（1） ?, β= 127.07（1）o, V=15086.2（6） ? 3, Z = 4, Dc = 2.976g·cm－3, ( = 3.316 mm－1, F（000） = 12963, the final R = 0.0585 and wR = 0.1490 for 5431 observed reflections. It contains a usual structural unit {Mo36}, which is linked to two eight-coordinated Gd3+ cations with the Gd-O distances from 2.31（5） to 2.46（5）
