Spontaneous self assembly of the {M<sub>2</sub>(µ-O)(µ-MeCO<sub>2</sub>)<sub>2</sub>}<sup>2+</sup>core. Synthesis, structure, and properties of the binuclear vanadium(<scp>III</scp>) complex
The green complex [L2V2(µ-O)(µ-MeCO2)2]I2·2H2O, where L represents N,N′,N″-trimethyl-1,4,7-triazacyclononane, is formed spontaneously on hydrolysis of LVCl3·dmf (dmf = dimethylformamide) in water in the presence of sodium acetate; characterization by X-ray crystallography showed the presence of the µ-oxo-di-µ-acetato-divanadium(III) core.
绿色的配合物[L 2 V 2(µ-O)(µ-MeCO 2)2 ] I 2 ·2H 2 O其中L代表N,N ',N '' -三甲基-1,4,7-三氮杂环壬烷。在乙酸钠存在下,在水中水解LVCl 3 ·dmf(dmf =二甲基甲酰胺)时自发形成;通过X射线晶体学表征表明存在μ-氧代-二-μ-乙酰基-二钒(III)核。
