anticorrosive plastics, arsonium, nanomaterials, antibacterial woods
A search of anticorrosive with antibacterial property of compounds motivated us to synthesize nanomaterials with quaternary compounds. The arsonium triiodides [(Ph3AsCH2I]I3 and [(i-Bu)3AsCH2I]I3 nanomaterials have been synthesized and characterized. The x-ray structures of [(Ph3AsCH2I]I3 and [(i-Bu)3AsCH2I]I3 have been determined. Crystals belong to the monoclinic (comp.1) system, space group P 21/n (No. 14) with a = 10.97 (1)Å, b=13.152 (1)Å, c=16.882 (1)Å , β=93.01 (1)o and to the triclinic system (comp.2), space group P-1 (No. 2) with a=8.413 (1)Å, b=9.109 (1)Å, c=15.876 (1)Å, α = 76.24 (1)o , β=75.60 (1)o, γ=75.26 (1)o. The structures were refined to an R value of 0.063 from 4082 (comp. I) and 0.091 from 4475 (comp.2) observed reflections. The As atom is coordinated tetrahedraly to the substituents and the anion has a linear structure. The synthesis of [R2(R’)AsCH2I]I3 (where R= R’ or R≠ R’) are described. The antibiocorrosive woods and plastics have possibility of the perspective application in synthesized compounds in bacterial resistant structures in homes and buildings. The test-microorganisms such as phitogen gram-positive - Staphylococus aurous, from gut’s group bacteria phitogen gram-negative - Esherichia coli, spore-forming bacteria – gram-positive Bacillus subtilis and gram-positive (from radiate mushrooms) Autinomyces griseus showed high toxicity of iodmethylenediamylphenylarsonium triiodide as antibacterial nanomaterials. It inhibited growth of Esherichia coli, Staphylococus aureus and Bacillus subtilis with minimal concentrations.
