Some ionic compounds MXY of the matlockite family (PbFCl) are characterized by the symmetry of the anions X and Y surroundings. If the cage around the ions X and Y are regular, the crystal is said to be 99regular:: and these conditions of symmetry give four equations adequate to compute the lattice
