Abstract

The preparation and physical and chemical properties of a square planar Ni(II) complex [Ni(C11H11NOS)]2 containing a Schiff base ligand derived from 2,4-pentanedione and 2-aminobenzenthiol are reported. This Schiff base ligand has three potential donor atoms. The dinegative ligand of 2-(2-mercaptophenyl)imino-4-pentanone coordinates to Ni(II) as a three dentate ligand. The structure was elucidated on the basis of spectroscopic data (IR, NMR and MS) and elemental analyses. The crystal and molecular structure were also obtained by X-ray single crystal diffraction method. The structure is best described as containing two planar Ni(II) centers in NOS2 coordination environments that share an edge formed by two bridging thiolates. © 2002 Elsevier Science B.V.
