Triphenyltin(IV) compounds with biologically active anionic groups: Crystal and molecular structures of thep-ethoxybenzoic acid, acetylsalicylic acid, phthalic acid and salicylaldehyde derivatives

μ-Phthalato-bis[tris(2-methyl-2-phenylpropyl)tin(IV)]

“…In the title unsubstituted phthalate, (I), all atoms lie in general positions, and both Sn atoms are four-coordinate in tetrahedral environments (Fig. The less bulky bis(triphenyltin) phthalate analogue also has its metal atom in a tetrahedral geometry (James et al, 1998). Bond dimensions, such as the covalent SnÐO distances, are similar to those found in thē uoro-substituted carboxylate.…”

Synthesis and Characterization of Triphenyltin(IV) Carboxylates with Isophthalic Acid and Benzoic Acid Derivatives: X‐ray Crystal Structures of 1D Supramolecular Chains

“…The Sn–O bond length Sn(1)–O(1) (2.082(3) Å) lies in the Sn–O covalent bond length, which proves that the oxygen atom is coordinated to the tin atom by a strong chemical bond. The other Sn–O bond length Sn(1)–O(2) (2.787(2) Å) is longer than Sn–O covalent bond length, but much shorter than the sum of the van der Waals radii (3.68 Å), and close to the distance between a coordinated oxygen atom and a central tin atom in other organotin complexes 28,29. The tin atom Sn(2) is linked to three phenyl groups and one oxygen atom, which leads to a distorted tetrahedral arrangement.…”

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

“…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]. The organotin(IV) dicarboxylates have been studied in considerable detail, and in general the reported organotin(IV) dicarboxylates exist as dinuclear [25] one-dimensional zigzag chain [26] and cyclic structures [27]. Recently, our interest has focused on triorganotin(IV) complexes containing dicarboxylate ligands which have an additional hetero-donor atom (e.g., N, O, S) residing on the R 0 group that is, potentially pentadentate ligands, in order to examine what effect the presence of the heteroatom has on the structure adopted by these complexes [28].…”
