摘要：
A new niobium cluster compound, [Al(CH3CN)5Br][Nb6Cl12iBr6a]·3CH3CN was synthesized and characterized by single-crystal X-ray diffraction and IR spectroscopy. Crystals of this cluster compound have triclinic symmetry with a = 8.8759(7), b = 12.300(1), c = 12.585(1) Å, α = 83.240(4), β = 71.231(4), and γ = 72.474(4)°. In this compound the charge of the mixed halide cluster anion, [Nb6Cl12iBr6a]2−, is compensated by that of the heteroleptic [Al(CH3CN)5Br]2+ complex cation, which has close to C4v symmetry. This complex cation can be considered as rather uncommon, since before only two compounds were known, which contain the chlorido analogue.
