Klimov A.V., Berdinskiy V.L. MAGNETIC STATES OF BUILDING BLOCKS OF THREE-NUCLEAR MOLECULAR ANTIFERROMAGNETS.The ground magnetic and spin states of triangular hetero-ionic complexes [M'(M")₂]L₃ containing ions M' and M" with different electron spins have been studied. These ions are supposed to interact via exchange interactions with negative exchange constants J and J'. Noncoplanar magnetic and spin structures are possible. Spin functions are independent of J'/J. The ratio J'/J affects only realization of one of the possible spin states. Such complexes with noncoplanar magnetic structures can be used for designing 2D and 3D lattices of new molecular ferrimagnets. Key words: molecular magnets, three-nuclear complexes, spin states.
