A cadmium complex bis(benzyltriethylammonium) bis(1,3‐dithiole‐2‐thione‐4,5‐dithiolato)‐cadmium(II) ((TEBA) 2 [Cd(DMIT) 2 ]) has been synthesized and its crystal structure has been determined by means of X‐ray single‐crystal diffraction. The central cadmium(II) ion coordinates with two DMIT, which constructed a distorted tetrahedron environment. Its third‐order nonlinear optical properties have been studied using Z‐scan technique with 20 ps pulses at wavelength 1064 nm. Its third‐order nonlinear susceptibility χ (3) value was determined to be 1.24 × 10 −19 m 2 V −2 , the figure of merit, χ (3) / α 0 , was estimated to be 2.64 × 10 −20 m 3 V −2 .
