Abstract

The triplesalophen complex [(baron^Me)Co^II₃] has been synthesized and characterized. The low-spin Co^II ions possess an ²A₂ ground state with the magnetic orbitals of d_yz type. These are well oriented for a strong π overlap with the bridging phloroglucinol, which results in the strongest ferromagnetic interactions by the spin-polarization mechanism for a 3d phloroglucinol complex.
