The square-planar organosilver(III) complex [trans-(CF3)2AgBr2] (16 electron) undergoes a marked stereochemical change upon coordination of an additional Br ligand. The resulting five-coordinate [(CF3)2AgBr3]2− complex (18 electron) exhibits trigonal bipyramidal geometry, which is unprecedented for AgIII. This five-coordinate compound also exhibits inverted ligand field.

具有倒置配体场的五配位化合物:银 (III) 的前所未有的几何结构



方形平面有机银(III)络合物[反式-(CF 3 ) 2 AgBr 2 ] - (16个电子)在额外的Br -配体配位后发生显着的立体化学变化。所得五配位[(CF 3 ) 2 AgBr 3 ] 2−络合物(18个电子)表现出三角双锥几何形状,这对于Ag III来说是前所未有的。这种五配位化合物还表现出反向配体场。
