Keywords: nickel dithiolatophenylcyclohexanedione bisdiphenylphosphinoethane diphenylphosphinomonosulfidemethane complex preparation redox potential; crystal structure nickel dithiolatophenylcyclohexanedione bisdiphenylphosphinoethane diphenylphosphinomonosulfidemethane complex.They researched the compound: 1,2-Bis(diphenylphosphino)ethane( cas:1663-45-2 ).Quality Control of 1,2-Bis(diphenylphosphino)ethane. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1663-45-2) here.
Four new heteroleptic Ni() complexes with general formula [Ni()(LL’)], L = 2-(methylene-1,1′-dithiolato)-5-phenylcyclohexane-1,3-dione (L1) and 2-(methylene-1,1′-dithiolato)-5,5′-dimethylcyclohexane-1,3-dione (L2); L’ = 1,2-bis(diphenylphosphino)ethane (dppe) and bis(diphenylphosphino)monosulfide methane (dppms) were synthesized and characterized by elemental anal. and spectroscopy (IR, UV-Vis, 1H, 13C{1H} and 31P{1H} NMR). All complexes 1-4 were characterized by PXRD and single crystal X-ray crystallog. The solid state mol. structures revealed distorted square planar geometry about the four-coordinate Ni(II) metal center together with rare Ni···H-C intra/intermol. anagostic interactions in axial positions. In these complexes supramol. structures were sustained by non-covalent C-H···O, C-O···H-O, C-H···π, C-H···π (NiCS2, chelate), π···π and H···H interactions. Their electrocatalytic properties were investigated for oxygen evolution reaction (OER) in which complex 2 showed the highest activity with 10 mA cm-2 at the potential of 1.58 V vs. In addition, complex 2 also exhibits an OER onset potential at 1.52 V vs.
Although many compounds look similar to this compound(1663-45-2)Quality Control of 1,2-Bis(diphenylphosphino)ethane, numerous studies have shown that this compound(SMILES:P(CCP(C1=CC=CC=C1)C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4), has unique advantages.
