prepared from MeLi and a stoichiometric amount of BiX3 in thf, react with 1,10-phenanthroline, 2,2′-bipyridyl or Me2NCH2CH2NMe2 (L−L) in thf or MeCN to give [BiMeX2(L−L)], which are poorly soluble in non-polar solvents. X-Ray structures of [BiMeBr2(L−L)] and of [BiMeCl2(Me2NCH2CH2NMe2)] show discrete square pyramidal molecules with apical methyl groups, and no intermolecular contacts within the sum
由MeLi制备的甲基二卤代铋,BiMeX 2(X = Cl或Br)和化学计算量的BiX 3在thf中与1,10-菲咯啉,2,2'-联吡啶或Me 2 NCH 2 CH 2 NMe 2(L- L)或MeCN中得到[BiMeX 2(L-L)],难溶于非极性溶剂。[BiMeBr 2(L-L)]和[BiMeCl 2(Me 2 NCH 2 CH 2 NMe 2)]显示具有顶甲基的离散方形锥体分子,并且在适当的范德华半径之和内没有分子间接触。BiMe 2 Br的结构是带有溴桥的1-D聚合物链,该桥在铋上包含伪三角锥型双锥体几何结构。BiMe 2 X与双齿N供体配体的反应导致歧化也形成[BiMeX 2(L–L)]。一个不寻常的[BiMeBr 4 ] 2-的阴离子在盐[李(H 2 O)(1,10-phen)的2 ] [李(1,10 -苯基)2(μ-溴)BiMeBr 3]·thf,被分离为副产物,显示出与一个
