Crystal structures of inorganic compounds containing cationic complexes with oxygen atoms inside a tetrahedron of metal atoms, or oxygen-centered groups [OM4], are reviewed. Types of a linkage of [OM4] tetrahedra into the structures were analysed, and a number of the differently built cationic complexes were identified. Rules for a linkage of [OM4] tetrahedra were formulated, and a detailed systematics of the cationic complexes in inorganic crystals was derived on their ground. A formation and a linkage of oxocentered tetrahedra in most of the crystal structures were considered for a first time. Statistics of bond distances and bond angles in [OM4] tetrahedra was discussed.
