In formulas like "AVnXm", "A" means coordinating atom, "V" means coordinated atom or lone pair, and "X" means its replacement by different atom (or atomic group which has the same effect on symmetry as alone atom).
Note that electronic and thus chemical properties can be different for molecules with the same coordination class. As an example CH3F molecule has tetrahedral coordination but its molecular orbitals and directions of chemical activity corresponds to linear antiprism double coordination (though the distribution of charge around F atom is spherically symmetric).
