have been determined. They are the first crystallographically characterized iron tricarbonyl trihalide complexes. fac-[FeII(CO)3X3]1− (X = Br, I) are fairly thermally stable and therefore lead themselves as excellent starting materials for the preparation of various iron carbonyl complexes since both the halide and carbonyl ligands are substitutionally labile.
                                    合成了摘要 fac-[FeII(CO)3X3]1− (X = Br, I) 并确定了它们的结构。它们是第一个晶体学表征的三羰基三卤化
铁配合物。fac-[FeII(CO)3X3]1- (X = Br, I) 是相当热稳定的,因此作为制备各种
羰基铁配合物的极好原料,因为卤化物和羰基
配体都是取代不稳定的。
