Abstract: A new complex bis(1,1-diethyl-3-(3-fluorobenzoyl)-thiourea) nickel (II) (NiL₂) has been synthesized and characterized by IR, ¹H NMR, ¹³C NMR spectra and elemental analysis. Structure of the complex has been determined by single crystal X-ray diffraction (CCDC 633339). The two ligand molecules adopt a cis-conformation bonded to the Ni(II) ion and the central nickel ion has four-coordination square-planar geometry contributed by two S and two carbonyl O atoms. Both the complex NiL₂ and its free ligand HL (1,1-diethyl-3-(3-fluorobenzoyl)-thiourea) exhibit powerful plant growth regulating activity towards the root of rape and compared with the free ligand HL. The complex NiL₂ displays more promoting activity in lower concentrations.
