The crystal structure of dimethylphenyltin(IV) acetate

Synthesis, characterization, and molecular structures of di- and triorganotin(IV) complexes with 9-anthracenecarboxylic acid: The structural diversity in organotin 9-anthracenecarboxylates

“…The tin-oxygen bond lengths of 2.2231(2) and 2.3800(2) Å is attributed to the unevenness in bonding; the latter value is in the range of Sn-O bond lengths, which have been reported for intramolecular bonds in triorganotin carboxylates [47]. The intramolecular tin-oxygen bond length [Sn(1)-O(2), 2.3800 Å ] is similar to those of trimethyltin(IV) and dimethylphenyltin(IV) acetates [24,48] but is slightly longer than that of triphenyltin acetate(IV) [49]. Although the oxygen-tin-oxygen skeleton is bent, 164.08 (7) [35] is probably imposed by anthracene group to minimize steric interactions.…”

“…Several authors have used various approaches for synthesis of organotin carboxylates, including reacting organotin chloride to carboxylic acid in the presence of sodium hydroxide or sodium salt of carboxylic acids. Alternatively, they were prepared by reacting organotin iodide to silver acetates [24]. However, in the latter approach, cleavage of aryl groups present some difficulties, consequently a milder synthetic approach has been used.…”

“…This clearly demonstrates the significant role of organic substituent groups on tin. Although synthesis and characterization of organotin carboxylates have been widely investigated, there are only a limited number of studies on the preparation of organotin carboxylates with mixed alkyl and aryl substituent groups on tin [22][23][24][25]. Probably this is because of the difficulties presented by the syntheses of mixed organic groups on tin entity.…”

Syntheses and characterization of triorganotin complexes: X-ray crystallographic study of triorganotin pyridinedicarboxylates with trinuclear, 1D polymeric chain and 2D network structures

“…Among them, the study of the structural chemistry of triorganotin carboxylates has received considerable attention owing to the various structural types that may be adopted in the solid state [12][13][14][15][16][17][18][19]. Although a large number of structural studies have been carried out on the triorganostannyl esters of monofunctional carboxylic acids [20], relatively little work has so far been undertaken on the triorganotin esters of dicarboxylic acids [21][22][23][24].…”

Structure of tri-n-butyltin(IV) 1-uracilacetate

“…A central question in the structural chemistry of triorganotin(IV) carboxylates is whether carboxylate groups will chelate to form monomers with four-coordinate tin or give five-coordinate polymers as a result of carboxylate bridging (Amini, Ng, Fidelis, Heeg, Muchmore, van der Helm & Zuckerman, 1989). Triphenyltin(IV) arylcarboxylates are generally monomeric molecules with tetrahedral tin (Ng, Kumar Das, van Meurs, Schagen & Strayer, 1989); the aryl group prefers to be conjugated to the carboxylate group and to be coplanar with it.…”
