This change can be explained by different cation radiuses in the octahedralcoordination site of garnet lattice.
这种规律性的变化可由石榴石晶格中处于八次配位时不同阳离子的配位半径不同作出解释。
2
O expresses the layers of all octahedral-coordination cations;
以O表示全部为阳离子八面体配位的层；

By use of these regulations and rules, the molecular configuration of coordination compounds with octahedral shape can be conveniently correlated with their rotatory direction.
