补充资料：外轨配合物和内轨配合物
根据L.C.鲍林的价键理论,具有八面体结构并有4个未成对电子的、顺磁性的[CoF6]3-,或有5个未成对电子的、顺磁性的[Fe(H2O)6]3+,其配位成键杂化轨道为4s4p34d2，所用d 轨道与s和p轨道是属于同一主能级的。这类具有nsnp3nd2形式的配合物(见配位化合物), 因为使用了外层的d轨道,所以叫做外轨配合物。两种配合物的杂化成键轨道分别如图所示。对于具有八面体结构且所有电子都是成对的、抗磁性的[Co(NH3) 6]3+， 或具有1个未成对电子的、 顺磁性的[Fe(CN)6]3-,其成键杂化轨道为3d24s4p3,使用了比s和p轨道低一级主能级层中的d轨道。这类具有(n-1)d2nsnp3型式的配合物,由于使用了内层的d轨道，所以叫做内轨配合物。
