The H-T phase diagrams for analogs of Prussian blue with two compensation points in an external magnetic field directed parallel to the easy axis are constructed for the first time in the mean field approximation. It is shown that, in this case, the H-T phase diagrams have a complex topology, including two triple points. The influence of the change in the chemical composition on the shape of the H-T phase diagram is investigated.
