Synthesis, crystal and molecular structures of the octanuclear cationic mixed-valence cobalt acetate complex

• A new octanuclear mixed-valence cobalt acetate complex of the cationic type [Co-4(II) Co4(III) (mu(4)-O)(4)(mu(3)-OMe)(4)(mu-OAc)(6)(H2O)(8)]F-2 center dot 10H(2)O ([I]F-2 center dot 10H(2)O) was prepared by crystallization from a solution of 'cobalt(III) acetate' in a Me2CO-MeOH-H2O-HF mixture and studied by X-ray diffraction. The crystals are monoclinic: space group C2/c, a = 17.222 angstrom, b = 16.836 angstrom, c = 16.586 angstrom, beta = 94.902 degrees, Z = 4, R = 4.37% (I > 2 sigma(I)). In the crystal, the I2+ complex cations, fluoride anions, and solvate water molecules form a three-dimensional (3D) coordination supermolecular system.
