“…[316] Further developments include the preparation of new epoxy polymers containing Cu(II) and Ni(II) ions by the addition of thiourea metal complexes into the polymer matrix, resulting in a material with good tensile strength and high thermal stability. [162] On the basis of the analysis of the vibrational spectra, it has been predicted that increasing conjugation and dissymmetry of the thiourea results in high nonlinear hyperpolarizabilities, [150,151] with promising applications of these compounds as nonlinear optical materials. 1-(Benzoyl)-3,3-dialkyl thioureas have been used in the design of liquid crystalline materials.…”

This review provides an overview of the chemistry, structure and potential applications of 1-(acyl/aroyl)-3-(mono-substituted) and 1-(acyl/aroyl)-3,3-(di-substituted) thioureas, with general formula R 1 C(O)N (1) HC(S)N (3) R 2 R 3 . In recent years, the title compounds have found extensive applications as ligands in coordination chemistry. The effect that nitrogen substituents exert on the intra-and intermolecular hydrogen-bonding interactions is discussed, including their role on the coordination properties displayed by these ligands. Novel applications of transition metal complexes bearing 1-(acyl/aroyl)-3-(mono-and di-substituted) thioureas are introduced. Biological aspects are also highlighted. As recently demonstrated, high-throughput screening assay and structure-activity analyses are feasible for this class of compounds. The chemical versatility of 1-(acyl)-3-(substituted) thiourea molecules and the derived metal complexes, together with the possibility of determining detailed structural properties, join biological applications in a promising interdisciplinary approach. The bibliography includes 382 references with emphasis on the literature appearing after 2007.

“…Some derivatives are biologically active, such as antifungal [6,7], antitumour [8][9][10], antiviral, antibacterial [11][12][13], pharmacological [14], herbicidal, and insecticidal properties [11][12][13]. In addition, some of the research groups have reported thermal behaviour [15][16][17][18] and the acidity constants [19] of ligands of some benzoylthiourea derivatives and their metal complexes [20][21][22][23][24][25][26][27][28][29][30].…”

New benzoyl thiourea derivatives and their nickel and copper complexes were synthesized. The structure of the synthesized compounds were confirmed by elemental analysis, FT-IR, and1H NMR techniques. Four of the synthesized compounds are analyzed by X-ray single crystal diffraction technique. WhereasN,N-dimethyl-N′-(4-fluorobenzoyl)thiourea,N,N-diethyl-N′-(4-fluorobenzoyl)thiourea, andN,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 ligand molecules form dimers through strong intermolecular hydrogen bonds such as N–H⋯S, C–H⋯O, and N–H⋯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 Å.

“…These ligands exhibit prevalent coordination systems such as neutral bidentate and monobasic bridging in some complexes [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Since the structural and conformational properties of acyl thioureas has been recognized, the use of transition metal complexes, including acylthiourea ligands, have been expanded in many different fields [9][10][11][12].…”

The compound N-(dibenzylcarbamothioyl)-3-methylbutanamide as a thiourea derivative was synthesized and structurally characterized by NMR and FT-IR spectroscopic techniques. The molecular structure of compound was also characterized by single crystal X-ray diffraction method. Crystal data for title compound C20H24N2OS: monoclinic, space group C2/c (no. 15), a = 19.6882(9) Å, b = 9.4045(4) Å, c = 19.5012(8) Å, β = 98.433(2)°, V = 3571.8(3) Å3, Z = 8, μ(CuKα) = 1.665 mm-1, 25057 reflections measured (9.168° ≤ 2Θ ≤ 144.196°), 3500 unique (Rint = 0.0322, Rsigma = 0.0200) which were used in all calculations. The final R1 was 0.0363 (I>2σ(I)) and wR2 was 0.0910 (all data). Intermolecular contacts obtained from X-ray single crystal diffraction study were also explored using both Hirshfeld surfaces and fingerprint plots. Hirshfeld surface analysis showed the occurrence of S···H, O···H and H···H contacts that display an important role to crystal packing stabilization of the thiourea derivative compound. In addition, the compound was evaluated for both their in-vitro antibacterial and antifungal activity.
