摘要：
Reaction of nickel (Ⅱ) acetate with S-methyl-β-N-(4 dimethy-laminophenyl) methlenedithiocarbazate gave a mononuclear complex [Ni (C11H14N3S2)2]. Crystal of the title compound belongs to monoclinic systern,space group C2/cwith cell parameters a= 18. 785 (1), b= 17. 274 (1 ), c= 8. 344 (1 ) A, β= 108. 64(2)°, V= 2565(1 ) A3, Z=4, Mr= 563. 36, Dc= 1. 459 g/cm3; μ=10. 05 cm-1 andF(000) = 1176. The final refinement with 2179 observed reflections is converged withR= 0. 044 and R.= 0. 069. X-ray crystal structure analysis revealed that the coordina-tion geometry of Ni (Ⅱ) is a square-planar with two equivalent Ni -N and Ni - Sbonds. The Schiff-base ligand loses a proton from its tautomeric thiol form and is coor-dinated to the nickel atom via the mercapto sulphur and the β-nitiogen.
