Synthesis, characterization, crystal structure and thermal behavior of N'-(4-chlorobenzoyl)_N,N-di N-di-n-butylthiourea and its nickel complex

Synthesis, characterization, crystal structure and thermal behavior of N'-(4-chlorobenzoyl)_N,N-di N-di-n-butylthiourea and its nickel complex

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 mono-clinic, space group $P2_1/c$ with a = 10.7457(5) Â, b = 15.5909(8) Â, c = 10.4536(5) Â, $beta$ = 104.398(1)°, and V = 1696.34(14) $A^3$ with Z = 4 for $d_{calc}$ = 1.280 g/cm3. NiL2 is a triclinic, space group P-1 with a = 8.561(3) Â, b = 16.643(6) Â, c = 25.723(9) Â, $alpha$ = 77.448(6)°, $beta$ = 84.077(7)°, 7 $gamma$= 88.684(6)°, and V = 3558(2) $A^3$ with Z = 4 for $d_{calc}$ = 1.326 g/cm3. The ligands coordinate to the metal atom in a bidentate manner, yielding an essentially neutral complex of the type $ML_2$. Thermal decomposition of related compounds was investigated by TG and DTA. The pyrolytic end product was identified by X-ray powder diffraction.
