Abstract
The synthesis and full characterization of the redox-active nickel triad mixed-ligand dithiolene complexes based on Bz2pipdt = 1,4-dibenzylpiperazine-3,2-dithione and dmit = 2-thioxo-1,3-dithiole-4,5-dithiolate ligands are reported. These complexes show a reversibly bleacheable solvatochromic peak and a remarkably high negative molecular first hyperpolarizability, whose values depend on the metal being highest for the platinum(II) compoundItems in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
