摘　　要：The title compound [Er4(m3-OH)4(Hpro)4(pro)2(H2O)7](ClO4)67H2O has been synthesized and its crystal structure was determined by X-ray diffraction study. It crystallizes in rhombohedral, space group R3, a = b = c = 12.7812(2) ? a = b = g = 100.067(1), V = 1978.19(5) 3, Z = 1, Mr = 2274.77, Dc = 1.909 g/cm3, F(000) = 1112, m = 4.506mm-1, the final R = 0.0405 and wR = 0.1068 for 3711 observed reflections (I > 2s(I)). Four Er3+ ions and four m3-OH display a Er4O4 cubane structural motif. Each proline interconnects two Er3+ ions.The title compound [Er4(m3-OH)4(Hpro)4(pro)2(H2O)7](ClO4)67H2O has been synthesized and its crystal structure was determined by X-ray diffraction study.
