The first dimeric mixed‐ligand zinc(II) complex of 1,3‐dithiole‐2‐thione‐4,5‐dithiolate (dmit) [Zn(dmit)(2,2′‐bpy)] 2 (2,2′‐bpy = 2,2′‐bipyridine) ( 1 ), which exhibits a good third‐order nonlinear refraction effect, was synthesized by a ligand exchange reaction between [(Et 4 N) 2 Zn(dmit) 2 ] and [Cu(2,2′‐bpy)(NO 3 ) 2 ]·2H 2 O. A Z ‐scanning measurement of complex 1 gives the third‐order nonlinear refraction index n 2 = 3.72 × 10 −18 m 2 /W and the real part Reχ (3) = 1.01 × 10 −12 esu. Crystal data for 1 : monoclinic, P 2 1 / c (No.14), a = 11.556(2) Å, b = 9.141(2) Å, c = 15.020(3) Å, β = 109.55(3)°, Z = 4. (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
