Synthesis, structure and NLO properties of a 1,3,5-substituted tricationic cobaltocenium benzene complex

© 2016 Elsevier B.V. Interested in the nonlinear optical properties of multinuclear metallocene-substituted complexes, we were successful in synthesizing the homotrinuclear coordination compound [1,3,5-tris(η5-2,4-cyclopentadien-1-yl)(η4-2,4-cyclopentadienyl-1-ethynyl)cobalt(I)]benzene (1) via a threefold nucleophilic addition to cobaltocenium cations. Upon hydride abstraction, the target compound [1,3,5-tris(η5-2,4-cyclopentadien-1-yl)(η5-2,4-cyclopentadienyl-1-ethynyl)-cobalt(III)]benzene tris(hexafluoridophosphate) (2) was obtained. Both complexes were fully characterized and, in continuation of previous investigations, investigated in terms of the influence of an octopolar arrangement of acceptor functions on the nonlinear optical activity of organometallic compounds.publisher: Elsevier articletitle: Synthesis, structure and NLO properties of a 1,3,5-substituted tricationic cobaltocenium benzene complex journaltitle: Journal of Organometallic Chemistry articlelink: http://dx.doi.org/10.1016/j.jorganchem.2016.07.021 content_type: article copyright: © 2016 Elsevier B.V.
