The subject of design and synthesis of molecular-based ferromagnets is one of the mainchallenges in the field of molecular materials. Along this line, the first important step issynthesizing molecular entities with a large spin in the ground state. Recently, Kahn haspointed out that it is possible for ABA linear trinuclar species with local spins2S_A>S_B+1/2 to stabilize a state of high-spin multiplicity with no need of imposingferromagnetic interactions between the nearest neighbor magnetic centers. Several ABA
