In the title complex, [Hg(NCS)2(CH4N2S)2], the HgIIatom is four-coordinated having an irregular four-coordinate geometry composed of four thione S atoms of two thiocyanate groups and two thiourea groups. The S—Hg—S angles are 172.02 (9)° for thetrans-thiocyanate S atoms and 90.14 (5)° for thecis-thiourea S atoms. The molecular structure is stabilized by an intramolecular N—H...S hydrogen bond, which forms anS(6) ring motif. In the crystal, molecules are linked by a number of N—H...N and N—H...S hydrogen bonds, forming a three-dimensional framework. The first report of the crystal structure of

Abstract:

The reaction of 1,3-Diisobutyl thiourea (Tu) with metal salts, {[CuX (X = Cl, I)], [ZnCl2] and [HgI2] in an appropriate stoichiometric ratio afforded the corresponding metal complexes [Tu2CuCl] (1), [Tu3CuI] (2), [Tu2ZnCl2] (3) and [Tu2HgI2] (4) in good yields. The FT-IR data show typically broad signals (3278–3288 cm−1) attributed to the involvement of NH bonds in extensive hydrogen bonding. The structures of complexes were proposed based on a spectroscopic data set. Compounds 1 and 2 were additionally characterized by single-crystal X-ray analysis.

For mercury the cases examined include RSHg(NO<sub>2</sub> ), [R<sub>3</sub> S][HgI<sub>3</sub> ] and HgCl<sub>2</sub> (tu) (tu = thiourea). The RSHg(NO<sub>2</sub> ) complex is probably a Hg-S-Hg bridged polymer incorporating nitrite ‘OO’ c

Abstract:

A study of the two polarographic prewaves of the Ni(II)–thiourea system has been made. The results were analysed by determining Koutecky's parameter from the ratio of the limiting current of the prewaves and the main wave. This parameter is considered an experimental rate constant and the influence of different variables on its value was analyzed. An electrochemical study of the prewaves was also made. Two formal mechanisms to explain both prewaves are proposed. Key words: polarographic prewaves, electrochemical kinetics, reaction mechanisms.

Abstract:

Due to the larger size of hetero atom and poor binding with metals, N2X2 type of core modified porphyrins show lesser tendency to form metal complexes. Mercury(II) complexes of symmetrical and unsymmetrical meso-tetraaryl-21,23-dithiaporphyrins are synthesized and characterized by the reaction of corresponding meso-tetraaryl-21,23-dithiaporphyrins with mercuric acetate in chloroform/methanol. These mercury complexes are well characterized by their UV-Visible spectra, fluorescence spectra, 1H NMR, 13C NMR and elemental analysis.

Abstract:

The interaction of nicotinic acid and thiourea with the chloride salts of Ca(II), Mg(II), Co(II), Ni(II), Cu(II), and Fe(III) ions led to the synthesis of a unique series of metal chelates. All formed metal complexes were clarified using a variety of analytical and spectral techniques, besides magnetic moment and thermal tests. The electronic and magnetic measurements indicated that the paramagnetic chelates (3) and (4), as well as the diamagnetic complexes (1) and (2), were responsible for the tetrahedral geometrical structure. The outcomes also led to the production of square-planar, and hig
