Novel 3-(2-thienyl) acrylic acid bridge di-triphenyltin(IV) {[(Ph)3SnCl)2COO]-[Et3NH]+, [(Ph)3SnCl2)]-[Et3NH]+} complex: XRD/HSA-interactions, physicochemical, thermal and POM/antifungal evaluation

The coordination reaction of Ph3SnCl with (E)-3-(thiophen-2-yl)acrylic acid as simple –COOH acid ligand in (Et)3N medium leads to formation of {[(Ph)3SnCl)2COO]-[Et3NH]+,[(Ph)3SnCl2)]−[Et3NH]+} complex matrix in high yield for the first time. FT-IR, UV–Vis, EDX, and a single XRD were used to characterize the prepared complex. Moreover, the complex was crystallized in the triclinic system P-1 with [a = 12.5191(4); b = 13.5491(5); c = 21.9805(8); α = 100.2790(10); β = 99.1470 (10) and γ = 100.4390(10)] the lattice cell parameters. The resulting environment of each Sn(IV) centers are a distorted trigonal bipyramid geometry where the ligand carboxylate part connected both Sn(IV) centers via O,O-bi-chelate mode trans to the Cl anions, meanwhile, the thiophen part was not coordinated to Sn(IV) anymore. Moreover, only Cl…H H-bonds with nonclassical mononuclear and classical binuclear type of interactions were recorded. Computationally, the Cl…..H predominant interactions were confirmed by Hirschfeld Surface Analysis (HSA). TG of the complex was evaluated under open atmosphere. The complex's antifungal activity against the pathogenic Fusarium oxysporum f.sp. albedins (FOA) showed more activity compared by the free ligand. Furthermore, POM theory was applied to evaluate the bioactivity and explain the experimental result of desired material against fungal.
