摘要：
The title compound [Er-4(mu(3)-OH)(4)(Hpro)(4)(pro)(2)(H2O)(7)](ClO4)(6).7H(2)O 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) Angstrom, alpha = beta = gamma = 100.067(1)degrees, V = 1978.19(5) Angstrom(3), Z = 1, M-r = 2274.77, D-c = 1.909 g/cm(3), F(000) = 1112, mu = 4.506mm(-1), the final R = 0.0405 and wR = 0.1068 for 3711 observed reflections (I > 2sigma(I)). Four Er3+ ions and four mu(3)-OH display a Er4O4 cubane structural motif. Each proline interconnects two Er3+ ions.
