    (Hindawi Ltd, 2013) Binzet, Gun; Kavak, Gulten; Kulcu, Nevzat; Ozbey, Suheyla; Floerke, Ulrich; Arslan, Hakan
    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, 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.

    Synthesis, characterization, crystal structure, and antimicrobial studies of novel thiourea derivative ligands and their platinum complexes
    (Taylor & Francis Ltd, 2018) Solmaz, Ummuhan; Gumus, Ilkay; Binzet, Gun; Celik, Omer; Balci, Gulten Kavak; Dogen, Aylin; Arslan, Hakan
    N, N-Di-R-N'-(4-chlorobenzoyl) thiourea (Di-R: diethyl, di-n-propyl, din-butyl and diphenyl) ligands (HL1-4) and their Pt(II) complexes (cis[ Pt(L1-4-S, O)(2)]) have been synthesized and structurally characterized by elemental analyses, FT-IR and NMR spectroscopy. HL2 ligand and cis-[ Pt(L-4-S, O)(2)] metal complex have been also characterized by a single-crystal X-ray diffraction study. HL2, C14H19ClN2OS, crystallizes in the monoclinic space group P2(1)/n (no. 14), with Z = 4, and unit cell parameters, a = 11.1405(16) angstrom, b = 9.7015(12) angstrom, c = 14.790(2) angstrom, beta = 106.547(7)degrees. The cis-[ Pt(L-4-S, O)(2)], C40H28Cl2N4O2PtS2 : triclinic, space group P-1 (no. 2), a = 8.9919(3) angstrom, b = 14.7159(6) angstrom, c = 15.7954(6) angstrom, a = 113.9317(18)degrees, beta = 97.4490(18)degrees, and. = 105.0492(16)degrees. Single crystal analysis of complex, cis-[ Pt(L1-4-S, O)(2)], revealed that a square planar coordination geometry is formed around the platinum atom by two sulfur and two oxygen atoms of the related ligands, which are in a cis configuration. In addition, the thiourea derivative ligands and their complexes were evaluated for both their in-vitro antibacterial and antifungal activity. The results have been reported, explained, and compared with fluconazole and ampicillin, used as reference drugs.
