Synthesis, characterization, and biocide activity of new dithiocarbamate-based complexes of In(III), Ga(III), and Bi(III) – Part III.

In this work, we describe the syntheses, characterization, and antifungal activity of [In{S2CNR(R1)}3] (1), [Ga{S2CNR(R1)}3] (2), [Bi{S2CNR(R1)}3] (3), [In{S2CNR(R2)}3] (4), [Ga{S2CNR(R2)}3] (5), and [Bi{S2CNR(R2)}3] (6) {R?=?Me; R1?=?CH2CH(OMe)2; and R2?=?2-methyl-1,3-dioxolane}. All complexes have been characterized using infrared and1H and13C spectroscopy, and the structures of1,3,4, and6have been authenticated by X-ray diffraction. The In(III)–dithiocarbamate bonding scheme depicts a distorted octahedral with asymmetric In(III)–S bonds and S–In–S angles. A pentagonal bipyramid is observed for the corresponding Bi(III) complexes with intermolecular Bi–S associations through the lone pair of electrons. The antifungal activities of1–6have been screened againstAspergillus niger,Aspergillus parasiticus, andPenicillium citrinum, and the results have been compared with those of nystatin and miconazole nitrate, as control drugs.
