SYNTHESIS, MOLECULAR AND ELECTRONIC-STRUCTURE OF COMPLEXES [LNAMIVNAL] (M=RU,OS H3L = 1,4,7-TRIS(4-TERT-BUTYL-2-MERCAPTOBENZYL)-1,4,7-TRIAZACYCLONONANE)

The trinuclear complexes [LNaM(IV)NaL] (M = Ru 1, Os 2) where L represents the hexadentate ligand 1,4,7-tris(4-tert-butyl-2-mercaptobenzyl)-1,4,7-triazacyclononane have been synthesized and 1 has been characterized by X-ray crystallography; complex 1 contains an octahedral M(IV)S6 central core and two trigonal-prismatic terminal LNa units with an N3S3 donor set; the electronic structure of the M(IV)S6 core (M = Ru, Os), has been established as S = 1 by temperature-dependent magnetic susceptibility measurements.
