A novel compound [(NH_4)_6][Gd_2Mo_(36)O_(112)(H_2O)_(20)]·52H_2O (1) was obtained from the reaction of (NH_4)_6Mo7O24·4H_2O 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)
