Abstract
Novel anhydrous trinuclear μ3-oxo complexes of Cr(III), Cr3(μ3-O)(CF3COO)6(CH3COOH)2(CF3COO) (I) and of Cr(III,III,II), Cr3(μ3-O)(CF3COO)6(CH3COOH)2(THF) (II) (where THF is (CH2)4O) are synthesized by anodic dissolution of metallic chromium in solutions of trifluoroacetic acid in acetonitrile and in tetrahydrofuran and their structures are studied by X-ray diffraction analysis. Complex I forms orthorhombic crystals with space group Pna21, a = 9.778(1) Å, b = 16.042(2) Å, c = 22.851(4) Å, Z = 4, R 1 = 0.0332; complex II crystallizes in monoclinic system: space group P21/c, a = 9.866(1) Å, b = 17.895(2) Å, c = 21.167(4) Å, β = 100.75(2)°, Z = 4, R = 0.0422. The average Cr-(μ3-O) distances in compounds I and II are almost equal (1.943(3) and 1.927(3) Å). An average length of the Cr-O bond in octahedral surrounding of metal atoms is different in complexes I and II (1.985(4) and 2.003(3) Å, respectively), which is specified by different oxidation states of the metal atom. The Cr⋯Cr distances lie in an interval of 3.366(1)−3.337(1) Å.
