A series of planar Ni(II) dithiolenes derived of maleonitriledithiol (mnt), benzene-1,2-dithiol (bdt) and toluene-3,4-dithiol (tdt) with bidentate P,P-ligands (dppe = 1,2-bis(diphenylphosphino)ethane, dppp = 1,3-bis(diphenylphosphino)propane, dppb = 1,4-bis(diphenylphosphino)butane, dpppn = 1,5-bis(diphenylphosphino)pentane) of the [Ni(P,P)(dithiol)] type have been synthesized. The compounds have been characterized by elemental analysis, IR and electronic spectroscopies, magnetochemical, conductivity measurements and thermal analysis. Single crystal X-ray analysis of [Ni(dpppn)(mnt)] confirmed a planar geometry of NiP2S2 chromophore. Possible practical applications such as use of these compounds for vulcanization accelerators and their anticholinesterase activity were evaluated.
Graphical abstractMolecular electronic properties of Ni(II) dithiolene complexes with P,P-ligands and their practical applications (anticholinesterase activity, vulcanization accelerators) were studied. The figure in the graphical abstract shows a molecular structure of [Ni(dppn))(mnt)] complex, dppn = l,5-bis(diphenylphodphino)pentane, mnt = maleonitriledithiol. The geometry of NiS2P2 chromophore is approximately planar.Figure optionsDownload full-size imageDownload as PowerPoint slide
