Öğe Synthesis and Characterization of Novel Thiourea Derivatives and Their Nickel and Copper Complexes(Hindawi Ltd, 2013) Binzet, Gun; Kavak, Gulten; Kulcu, Nevzat; Ozbey, Suheyla; Floerke, Ulrich; Arslan, HakanNew benzoyl thiourea derivatives and their nickel and copper complexes were synthesized. The structure of the synthesized compounds were confirmed by elemental analysis, FT-IR, and H-1 NMR techniques. Four of the synthesized compounds are analyzed by X-ray single crystal diffraction technique. Whereas N,N-dimethyl-N'-(4-fluorobenzoyl) thiourea, N, N-diethyl-N'-(4-fluorobenzoyl)thiourea, and N,N-di-n-butyl-N'-(4-fluorobenzoyl)thiourea crystallize in the monoclinic system, bis(N,N-di-n-propyl-N'-(4-fluorobenzoyl)thioureato) nickel(II) complex crystallizes in the triclinic system. These ligandmolecules formdimers through strong intermolecular hydrogen bonds such as N-H center dot center dot center dot S, C-H center dot center dot center dot, and N-H center dot center dot center dot O. Moreover, there are different types of intramolecular interactions in the crystal structures. Bis(N,N-dimethyl-N'-(4-fluorobenzoyl)thioureato) nickel(II) complex has a nearly square-planar coordination. The distance of nickel atom from the best plane through the coordination sphere is 0.029 angstrom.Öğe Synthesis and single crystal structure analysis of three novel benzoylthiourea derivatives(Tubitak Scientific & Technological Research Council Turkey, 2009) Kavak, Guelten; Ozbey, Sueheyla; Binzet, Guen; Kulcu, NevzatN,N-dimethyl-N'-(2-methylbenzoyl)thiourea, C11H14N2SO (HL1), N,N-dibutyl-N'-(2-methylbenzoyl) thiourea, C17H26N2SO (HL2), and N,N-dihexyl-N'-(2-methylbenzoyl) thiourea, C21H34N2SO (HL3) were synthesized and characterized by elemental analysis, spectroscopic methods (FT-IR, NMR), and single crystal X-ray diffraction. Compound HL1 crystallizes in the monoclinic system, space group P2(1)/c, Z = 4. Compound HL3 also crystallizes in the monoclinic system, space group P2(1)/n, Z = 8 with 2 independent molecules in the asymmetric unit. Compound HL2 crystallizes in the orthorhombic system, space group Penn, Z = 8. In all compounds, molecules form dimers through the strong intermolecular N-H center dot center dot center dot S hydrogen bonds. Moreover, there are different types of intra-and inter-molecular interactions in the crystal structures, and so the molecules of the 3 compounds also pack differently.Öğe Synthesis and Structures of N,N-dialkyl-N?-(2-methylbenzoly, 4-flourobenzoyl) thiourea derivatives.(Int Union Crystallography, 2009) Kavak, Gulten; Binzet, Gun; Kulcu, Nevzat; Ozbey, Suheyla[Abstract Not Available]
