Abstract
The reaction of monooxidized thioyl (4-CH3)C6H3N-2-NH(P(S)Ph2) (1) ligand with MCl2(COD)(M = Pd, Pt) in equimolar ratio resulted in cis-[MCl2{1-κ2S,Npy}] (M = Pd (2), Pt(3)) complexes. Also, The reaction of 1 with HgX2 (X = Cl, I) produced cis-[HgX2{1-κ2S,Npy }] (X = Cl(4), I(5)). Complexes 2–5 have been isolated and characterized by multinuclear NMR (1H, 13C, and 31P) and IR spectroscopy. The molecular structures of 2, 4, and 5 were determined using single X-ray crystallography. 4 and 5 are the first structurally defined instances of this type of κ2S,Npy -bidentate ligand with Hg(II) metal complexes. The new palladium(II) complex 2 as a pre-catalyst in the Suzuki cross-coupling process was also investigated.
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.
