中心离子周围的配位空间可分解出一系列相互接触的圆锥座位。应用位级图研究了内锁座位的简并、分裂、转化和对称性。在弱共价键化合物中,占据座位SAS(立体角系数扣)值最太的异构体有利于配体堆积。最小占据座位与最大空座位的差值可用作判断化合物稳定性的标准。 The coordination space around the center ion can disassemble a series of conical seats in contact with each other. Bitmap was applied to study the degeneracy, splitting, transformation and symmetry of the internal locking seat. Among the weakly covalent compounds, the isomer that occupies the most SAS value of the seat favors the packing of ligands. The difference between the minimum occupied seat and the largest empty seat can be used as a criterion for judging the stability of the compound.
