•New complexes with the dimerized quinoxaline-2,3-dithiolate ligand are synthesized.•The dinuclear complexes show the new κ2(S, N)-coordination mode.•The magnetic properties of the complexes are studied.
New dinuclear complexes with the bridging S―S coupled and dimerized quinoxaline-2,3-dithiolate (dsqdt) ligand, [TpPh2M(dsqdt)MTpPh2] (TpPh2 = hydro-tris(3,5-diphenylpyrazol-1-yl)borate; M = Co, 1; M = Ni, 2; M = Mn, 3), were prepared. X-ray crystal structure studies for complexes 1–3 indicate that the dsqdt ligand forms the unique κ2-coordinated mode through S and N atoms from the same qdt unit. The absorption spectra, redox behavior and magnetic properties of the compounds are reported.
Graphical abstractThree dinuclear complexes with the bridging S―S coupled and dimerized quinoxaline-2,3-dithiolate ligand (dsqdt) have been synthesized and structurally characterized. The dsqdt ligand shows the new κ2(S, N)-coordination mode. The absorption spectra, electrochemical and magnetic properties for all complexes are studied.Figure optionsDownload full-size imageDownload as PowerPoint slide
