Abstract
The treatment of metal chlorides MCl2 or metal chlorido complexes M(bpy)Cl2 (M = Mn, Ni, Cu, bpy = 2,2′-bipyridyl) with TlPF6 in acetonitrile to precipitate TlCl, followed by addition of excess nitrosobenzene, yielded monometallic or bimetallic azodioxide complex salts of the form [M(az)4](PF6)2, [M(bpy)2(az)](PF6)2, and [{M(bpy)(az)(μ-Cl)}2](PF6)2 (az = cis-N,N′-diphenylazodioxide), which have been structurally characterized via single-crystal X-ray diffraction. The method of activation of chloride salts or chlorido complexes by chloride abstraction with Tl+, followed by the addition of nitrosobenzene, continues to be an effective strategy for the synthesis of azodioxide complexes, and it has enabled the synthesis of the first structurally characterized azodioxide complexes of any metals of Groups 7, 10, or 11.
期刊介绍:
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
