A new approach to divalent thio-azo ligands; Ni(dpesdt)2
Résumé
The preparation of a new bis(2-pyridylethylsulfanyl)-1,3-dithiole-2-one (1) and the first example of a tetra-azo substituted bisdithiolene transition metal complex, Ni(dpesdt)2 (2) are reported. This complex crystallizes in two polymorphs, one is triclinic, and the other is monoclinic, P21/n space group.
