✦ Synopsis

A new model for the first-order transitions between the low-spin and high-spin phases of molecular crystals of some transition metal complexes is proposed. Tbe abrupt spin transitions (or those exhibiting thermal hysteresis) are attributed to first-order transitions between the different crystal phases with the sublattice order. The necessary conditions for these transitions to take place are formulated in terms of intramolecular parameters of the spin transition and intermolecular interactions.

A series of the d 6 iron(I1) complexes with bulky organic ligands (like [ Fe(bzpy),(NCS),]) can exist in two spin forms: in the low-spin ( S = 0) form at low temperature and in the high-spin ( S = 2) form at high temperature. In the crystal phase, the transition between these two forms may be either
