Boron Cluster Anions [B10X10]2– (X = H, Cl) in Manganese(II) Complexation with 2,2'-Bipyridyl

详细

The complexation of manganese(II) with 2,2'-bipyridyl in the presence of the [B₁₀H₁₀]^2– and [B₁₀Cl₁₀]^2– boron cluster anions has been studied in acetonitrile. The effect of the ratio of reagents on the composition and structure of final complexes has been shown. Mono- and binuclear manganese(II) complexes [(Mn(Bipy)₃]²⁺ and [Mn₂(Bipy)₄Cl₂]²⁺ have been synthesized with the boron cluster anions as counterions. The X-ray diffraction studies have been performed for complexes [Mn(Bipy)₃][B₁₀Cl (I)₁₀] (I), [Mn(Bipy)₃][B₁₀Cl₁₀]_0.5[B₁₀Cl₉H]_0.5 · CH₃CN (III· CH₃CN), and [Mn₂(Bipy)₄(µ-Cl)₂][B₁₀Cl₁₀] · 2CH₃CN (IV ⋅ 2CH₃CN) (CIF files CCDC nos. 1868278 (I), 1868279 (III · CH₃CN), 1868280 (IV · 2CH₃CN)). Thermal properties of complex I have been studied.
