Pentacoordinated molecules. 54. Pentacoordinated structures of triphenyltin esters of anthranilic acid, o-(dimethylamino)benzoic acid, and p-aminobenzoic acid formed by intramolecular carboxylate group coordination

Synthesis and characterization of a novel spring-like organotin complex containing guest benzene molecules

“…The O-Sn-O angles [173.8(15)°-179.3(15)°] are close to linear arrangements. The Sn-C bond lengths [2.02(6)-2.23 (5)] Å are consistent with those reported in other triorganotin carboxylates [25][26][27]. It should be note that although the carboxylic acid ligand has a heterocyclic nitrogen atom, the nitrogen atom does not has an obvious interaction to the center tin atom, perhaps the steric hindrance from the phenyl groups blocks the nitrogen atom from coordinating to the tin atom.…”

Syntheses and structural characterization of organotin(IV) complexes derived from the self-assembly of 2,4-diethylglutaric acid, phthalyl-glutamic acid and trialkyltin salts

“…The SneO distance [Sn(1)eO(1) 2.222(18) Å] is similar to the distances between bonding O atoms and central Sn atoms in other organotin complexes [9] but is much shorter than the sum of the van der Waals radii of Sn and O [16]. The SneC bond lengths [1.866(9)-2.01(3) Å] are consistent with those reported in other triorganotin carboxylates [18,19]..…”

Self-assembly of a novel 2D network polymer: Syntheses, characterization, crystal structure and properties of a four-tin-nuclear 36-membered diorganotin(IV) macrocyclic carboxylate

“…3) [39e44], in which all tin atoms and carboxylate groups are included. Besides these weak intermolecular Sn (2) (6) A] [27], being significantly shorter than the sum of the van der Waals radii for tin and oxygen atoms (3.70 A) [48], therefore these oxygen atoms can be considered as bonding. The geometry found about the tin atom in the complex 1 is best described as a skew-trapezoidal bipyramid geometry and closely resembles those found for the structures of n-Bu 2 Sn-(O 2 CCH 2 SC 6 H 5 ) 2 [49] …”
