Synthesis and Structure of [Er4(μ3-OH)4(Hpro)4(pro)2(H2O)7](ClO4)6·7H2O
The title compound [Er4(μ3-OH)4(Hpro)4(pro)2(H2O)7](ClO4)6@7H2O 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), α = β = y= 100.067(1)°, V= 1978.19(5)(A)3, Z = 1, Mr = 2274.77, Dc = 1.909 g/cm3, F(000) = 1112,μ = 4.506mm- 1, the final R = 0.0405 and wR = 0.1068 for 3711 observed reflections (Ⅰ＞ 2σ(Ⅰ)). Four Er3+ ions and four μ3-OH display a Er4O4 cubane structural motif. Each proline interconnects two Er3+ ions.
