The nickel(Ⅱ) complex with the new ligand of S-benzyl-β-N-[10-ethylphenothiazine-3-methylene]dithiocarbazate(HL) crystallizes in the triclinic system, space group P1-with a = 7.516(1), b = 11.322(1), c = 13.366(1) (A),α= 84.818(1),β= 81.688(1), y= 76.037(1)°, V= 1090.26(3) (A)3, Z = 1, Dc=1.413 g/cm3, F(000) = 482,μ(MoKα)= 0.774 mm-1 (λ= 0.7103(A)),R = 0.0573 and wR =0.1375 for 3357 observed reflections withⅠ≥ 2σ(Ⅰ). The HL has lost a proton from its tautomeric thiol form and acts as a single negatively charged bidentate ligand coordinating to the nickel ion via the mercapto sulfur and β-nitrogen atoms. The geometry around Ni(Ⅱ) is almost square-planar with two equivalent Ni-N and Ni-S bonds. The nonlinear absorption of HL and NiL2 solutions (in DMF) was measured by open-aperture Z-scan technique at the wavelength of 532 nm.
