本文报道了从“醋酸钴”中分离出对称中性立方化合物[Co-4(mu(3)-O)(4)(mu-CH3CO2)(4)(C5H5N)(4)]和三聚物六氟磷酸盐（R = 0.078, R = 0.073）的偏立方化合物[Co-3(mu(3)-O)(mu- oh)(3)(mu-CH3CO2)(CH3CO2)(C5H5N)(6)]（2+）的单晶x射线衍射表征（R = 0.087, R-w = 0.084）。立方烷结晶为氯仿溶剂化物[Co-4(mu(3)-O)(4)(mu- ch3co2)(4)(C5H5N)(4)]。5CHCl(3)，而部分立方烷结晶为其水溶剂，[Co-3(mu(3)-O)(mu- oh)(3)(mu-CH3CO2)(CH3CO2)(C5H5N)(6)][PF6](2)。2 h (2) O。cubane和部分cubane的平均Co .。Co距离分别为2.818(8)、2.683(6)、2.918(6)、2.767(5)埃，Co-mu(3)-O平均距离分别为1.86、1.91埃。1998爱思唯尔科学有限公司版权所有。
The isolation from "cobalt(III) acetate" and characterisation by single crystal X-ray diffraction (refined to R = 0.087, R-w = 0.084) of the symmetric neutral cubane, [Co-4(mu(3)-O)(4)(mu-CH3CO2)(4)(C5H5N)(4)], and of the hexafluorophosphate salt (refined to R = 0.078, R, = 0.073) of the trimeric dication, the partial cubane [Co-3(mu(3)-O)(mu-OH)(3)(mu-CH3CO2)(CH3CO2)(C5H5N)(6)](2+), are reported. The cubane crystallises as its chloroform solvate, [Co-4(mu(3)-O)(4)(mu-CH3CO2)(4)(C5H5N)(4)]. 5CHCl(3), whilst the partial cubane crystallises as its water solvate, [Co-3(mu(3)-O)(mu-OH)(3)(mu-CH3CO2)(CH3CO2)(C5H5N)(6)][PF6](2) . 2H(2)O. The cubane and partial cubane dication have average Co ... Co distances of 2.818(8), 2.683(6) and 2.918(6), 2.767(5) Angstrom, respectively, and average Co-mu(3)-O distances of 1.86 and 1.91 Angstrom, respectively. (C) 1998 Elsevier Science Ltd.
