Özet:

 

We report the synthesis, structural characterization and  thermal behavior of N'-(4-chlorobenzoyl)-N,N-di-n-butylthiourea (HL)  and its nickel complex (NiL2).  Some physical properties of the  prepared compounds were investigated using elemental analyses, IR,  1H-NMR, and magnetic susceptibility.  The molecular structures of HL  and NiL2 were determined by single crystal X-ray diffraction.  HL is  a monoclinic, space group P21/c with a = 10.7457(5) Å, b = 15.5909(8)  Å, c = 10.4536(5) Å, b = 104.398(1)°, and V = 1696.34(14) Å3 with  Z = 4 for dcalc = 1.280 g/cm3.  NiL2 is a triclinic, space group  P-1 with a = 8.561(3) Å, b = 16.643(6) Å, c = 25.723(9) Å, a =  77.448(6)°, b = 84.077(7)o, g = 88.684(6)°, and V = 3558(2)  Å3 with Z = 4 for Dcalc = 1.326 g/cm3.  The ligands coordinate to  the metal atom in a bidentate manner, yielding an essentially neutral  complex of the type ML2.  Thermal decomposition of related compounds  was investigated by TG and DTA. The pyrolytic end product was  identified by X-ray powder diffraction.
