6-iPr2-C6H3)}(μ-Cl)]2[(μ-Cl)2Co(THF)2] (4) was obtained in high yields. Complexes 3a–e have high-spin electronic configurations both in solution and in the solid state. X-ray diffraction studies of complexes 3a,e confirmed distorted tetrahedral coordination geometries. Complex 4, on the other hand, is a linear trinuclear Co(II)–Co(II)–Co(II) complex with two terminal distorted tetrahedral four-coordinate sites and
