The interplay of thiophilic and hydrogen bonding interactions in the supramolecular architecture of phenylmercury 4-hydroxypiperidine dithiocarbamate
摘要:
A new phenylmercury(II) dithiocarbamate complex [PhHg(S2CN(CH2)(4)CH(OH)], (1) has been synthesized and characterized by elemental analyses, IR, H-1 and C-13 NMR spectroscopy and X-ray crystallography. The crystal structure of 1 shows a linear arrangement at the Hg(II) centre of the molecule through bonding of the sulphur atom of the dithiocarbamate ligand and the carbon atom of the aromatic ring. Weak intermolecular thiophilic Hg center dot center dot center dot S interactions lead to a "head-to-tail" dimer and the presence of a hydroxyl group at the periphery of piperidine moiety generates a 1D-chain network through intermolecular O center dot center dot center dot H interactions. The nature of weak intra- and intermolecular Hg center dot center dot center dot S, H center dot center dot center dot S and intermolecular O center dot center dot center dot H interactions have been assessed with the help of ab initio calculations and atoms-in-molecules (AIM) approach.

New single-source precursor for bismuth sulfide and its use as low-cost counter electrode material for dye-sensitized solar cells
摘要:
One new homoleptic [Bi(dtc)(3)] (1) (dtc = 4-hydroxypiperdine dithiocarbamate) has been synthesized and characterized by microanalysis, IR, UV-Vis, H-1 and C-13 spectroscopy and X-ray crystallography. The photoluminescence spectrum for the compound in DMSO solution was recorded. The crystal structure of 1 displayed distorted octahedral geometry around the Bi(III) center bonded through sulfur atoms of the dithiocarbamate ligands. TGA indicates that the compound decomposes to a Bi and Bi-S phase system. The Bi and Bi-S obtained from decomposition of the compound have been characterized by pXRD, EDAX and SEM. Solvothermal decomposition of 1 in the absence and presence of two different capping agents yielded three morphologically different Bi2S3 systems which were deployed as counter-electrode in dye-sensitized solar cells (DSSCs).

One heteroleptic Ni(II) dppe dithiocarbamate complex cation [NiS2CN(CH2)(4)CHOH)}(dppe)](+) with three different counter anions viz. PF6 (1), BPh4 (2) and BF4 (3) have been synthesized and characterized by microanalysis, IR, UV-Vis, H-1, C-13 and P-31 NMR spectroscopy and X-ray crystallography. The crystal structure of 2 displayed distorted square planar geometry around Ni(II) center bonded through sulfur atoms of the dithiocarbamate ligand and two phosphorus atoms of the dppe. TGA results indicated that all the three compounds display loss of solvents at the outset and decompose to Ni-S phase systems. The nickel sulfides obtained from decomposition of 1-3 have been characterized by pXRD and SEM. The effect of the bulkiness of the counter anions on the phase and morphology of decomposed product have been observed using pXRD and SEM analysis. The UV-Vis and photoluminescent spectroscopy of the three decomposed product have been performed. (C) 2014 Published by Elsevier B.V.
