A series of organotin(IV) complexes have been synthesized by reacting potassium o-isobutyl carbonodithioate with di- and triorganotin halides in methanol under stirring conditions. The newly synthesized complexes have been characterized by elemental analysis, FT-IR, NMR (1H and 13C) and X-ray crystallography. The FT-IR results show that the ligand acts as bidentate in complexes 1-3 and monodentate in complexes 4 and 5, which were also confirmed by theoretical calculations. The NMR data reveal four and six coordinated geometries in solution. A HOMO-LUMO study shows that all the complexes are stable. Biological screenings demonstrate that, with a few exceptions, all the complexes show significant activity against various bacterial and fungal strains. The synthesized complexes were also found to be effective antioxidants of the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH). All the complexes have been assayed for antileishmanial activity in vitro and found some promising results. The UV-Vis studies confirmed that the ligand and its complexes bind to DNA via intercalative interactions, resulting in hypochromism and minor red shifts.

We present a simple, easily scalable route to monodisperse copper sulfide nanocrystals by the hot injection of a series of novel copper(I) xanthate single-source precursors [(PPh3)2Cu(S2COR)] (R = isobutyl, 2-methoxyethyl, 2-ethoxyethyl, 1-methoxy-2-propyl, 3-methoxy-1-butyl, and 3-methoxy-3-methyl-1-butyl), whose crystal structures are also reported. We show that the width of the obtained rods is dependent on the length of the xanthate chain, which we rationalize through a computational study, where we show that there is a relationship between the ground-state energy of the precursor and the copper sulfide rod width.

Paragraph 0030, (2019/03/02)
The invention discloses a water soluble triazine amino benzene sulfonic acid alkali metal salt derivative and a preparation method and application thereof. The invention relates to a synthesis process and application of an amino benzene sulfonic acid sodium and xanthonic acid group-containing triazine derivative, and is characterized in that: the 2-alkyl xanthate-4, 6-diamino benzene sulfonic acid alkali metal salt-1,3,5-s-triazine has the following structural formula shown in the specification, wherein X is Na, R is C1-C4 straight chain or branched chain alkyl. The preparation method is as follows: using cyanuric chloride, amino benzene sulfonic acid and potassium alkyl xanthate with the molar ratio of 1: 1.1: 2-2.1 as raw materials for reaction in an organic solvent. The amino benzene sulfonic acid sodium-containing triazine derivative can be used as additives used in pure water, water-glycol, synthetic ester, lithium base grease or calcium base grease, and by compounding with other water-based lubricant additives, the water soluble triazine amino benzene sulfonic acid alkali metal salt derivative has good abrasion resistance, extreme pressure resistance, corrosion resistance, and oxidation resistance. The synthesis process has the advantages of simple operation, high yield, and easy control of reaction condition.
