In the title compound, K(9)Al(3)(PO(4))(6), the anionic substructure is built of inter-linked [PO(4)] and [AlO(4)] tetra-hedra. Each O atom of the [AlO(4)] tetra-hedron is common to a positionally different [PO(4)] tetra-hedron; thus, each [AlO(4)] tetra-hedron is surrounded by four positionally different [PO(4)] tetra-hedra. On the other hand, each [PO(4)] tetra-hedron shares its two O atoms with two positionally different [AlO(4)] tetra-hedra; the other two phosphate O atoms are terminal ones coordinated by K atoms. The terminal O atoms are usually closer to the K atoms than the bridging O atoms between the [AlO(4)] and [PO(4)] tetra-hedra. There are nine symmetry-independent K atoms in the structure. The coordination numbers of the K atoms are 6 or 7 or 8 up to a distance of 3.31 Å. There are channels in the anionic substructure oriented along the [10] direction that are filled by K atoms.
在标题化合物K₉Al₃(PO₄)₆中，阴离子亚结构由相互连接的[PO₄]和[AlO₄]四面体构成。[AlO₄]四面体的每个O原子与一个位置不同的[PO₄]四面体共用；因此，每个[AlO₄]四面体被四个位置不同的[PO₄]四面体包围。另一方面，每个[PO₄]四面体与两个位置不同的[AlO₄]四面体共用其两个O原子；另外两个磷酸根O原子是由K原子配位的端基O原子。端基O原子通常比[AlO₄]和[PO₄]四面体之间的桥连O原子更靠近K原子。结构中有九个独立的K原子。K原子的配位数在距离为3.31 Å时为6或7或8。阴离子亚结构中沿[10]方向有通道，这些通道被K原子填充。
