Synthesis of the anisobidentate compound bis(2-amino-cyclopent-1-ene-carbodithioate)diethyltin (IV). Experimental and theoretical study

Synthesis of Methyldopa–Tin Complexes and Their Applicability as Photostabilizers for the Protection of Polyvinyl Chloride against Photolysis

“…The difference (Δv) between the asymmetric (asym) and symmetric (sym) vibration frequencies of the COO − group was calculated to be between 237 and 285 cm −1 . A value of Δv in this range indicates an intermediate state between monodentate and bidentate (anisobidentate) asymmetry [ 49 , 50 ].…”

Influence of intramolecular Sn–chalcogen interactions on the conformational preferences for three diorganotin(IV) xanthates

“…Particularly for tin functions up to D and F are used. The combination of these basis sets with the SDD ECP has proven to yield good results in the theoretical description of diorganotin compounds [20]. Table 1 shows a selection of data for the different geometry optimizations computed on compound (1) at the three possible coordination patterns.…”

Chlorodiphenyltin(IV) and triphenyltin(IV) complexes of N-alkylated 2-amino-1-cyclopentene-1-carbodithioic acids: synthesis, spectroscopic characterization and X-ray studies

“…The later pattern can be isobidentate or anisobidentate and this pattern is more frequently observed for Main Group Metals [6]. In recent years, the organotin complexes of the ACDA and its derivatives have been synthesized and characterized by X-ray crystallography [8][9][10][11][12]. In continuation of our interest in synthesis and X-ray structures of the organotin(IV) derivatives of the sulfur donor ligands, we report the synthesis and molecular structures of the phenyltin derivatives with 2-N-isopropylamino-1-cyclopentene-1-carbodithioic acid (L 1 H) and 2-N-secbutylamino-1-cyclopentene-1-carbodithioic acid (L 2 H) [13][14][15] (Scheme 1).…”
