Facile dissociation of [(LNi(II))2E2] dichalcogenides: evidence for [LNi(II)E2] superselenides and supertellurides in solution.
Easy breakage to open-shells: The diamagnetic butterfly-like dichalcogen complexes 1 (E = Se) and 2 (E = Te) with a {Ni(II)(2)E(2)} core, undergo facile dissociation in solution via spin crossover to give the unprecedented mononuclear paramagnetic superselenide and supertelluride species 1' and 2', respectively, along with the nickel(I) fragment [LNi(I)]; R = 2,6-diisopropylphenyl.
