Crystal structure and third-order nonlinear optical property study of a copper complex constructed by DMIT ligand

► A copper complex constructed by the ligand: 1,3-dithiole-2-thione-4,5-dithiolato (DMIT) was synthesized. ► Crystal structure has been determined. ► Third-order nonlinear optical property has been studied by Z-scan technique with 20 picosecond pulses at wavelength 1064 nm.
