Synthesis, molecular and electronic structure of complexes [LNaMIVNaL](MRu,Os; H3L = 1,4,7-tris(4-tert-butyl-2-mercaptobenzyl)-1,4,7-triazacyclononane)

Abstract

The trinuclear complexes [LNaM^IVNaL](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^IVS₆ central core and two trigonal-prismatic terminal LNa units with an N₃S₃ donor set; the electronic structure of the M^IVS₆ core (M = Ru, Os), has been established as S= 1 by temperature-dependent magnetic susceptibility measurements.
