Structure of triphenyltin(IV) 3-pyridinecarboxylate

Preparation and structural characterization of [Ph3Sn(IV)]+ complexes with pyridine-carboxylic acids or hydroxypyridine, -pyrimidine and -quinoline

“…Compounds 1, 4, and 7-10 were obtained as single crystals, while the others are amorphous solids. The synthesis and X-ray diffraction analysis of 8-10 were already reported [6][7][8]. The X-ray diffraction analysis of 9 and 10 showed that the Sn(IV) is penta-coordinated in distorted Tbp environment, in which the bulky phenyl groups are in equatorial positions.…”

Synthesis and characterization of di‐n‐butyltin(IV) complexes with 4′/2′‐nitrobiphenyl‐2‐carboxylic acids: X‐ray crystal structures of [{(n‐C4H9)2Sn(OCOC12H8NO2−4′)}2O]2 and (n‐C4H9)2Sn{OCOC12H8NO2−4′}2

“…Probably, the separation between the two sets of resonances was too small to be resolved. The 1 J( 119 Sn, 13 C) values are in the expected region for these compounds. 30 The C-Sn-C angles θ have been calculated by applying the Holecek equation, 30 and these values suggest a non-linear arrangement.…”

“…All these newly synthesized complexes were off-white air-and moisture-stable solids and were identified and characterized with melting points and elemental analyses, IR data and 1 H, 13 C and 119 Sn NMR data. The compounds 1 and 3 were soluble in organic solvents.…”

Tris(2-methyl-2-phenylpropyl)(pyridine-3-carboxylato)tin(IV)

“…There are no intermolecular SnÁ Á ÁN interactions in the crystal structure of (I); such interactions are found in triphenyltin 3-pyridinecarboxylate (Ng et al, 1989), tribenzyltin 3-pyridinecarboxylate (Yin et al, 2003) and tri(2fluorobenzyl)tin 3-pyridinecarboxylate (Yin et al, 2004). acid (0.25 g, 2 mmol) in benzene (50 ml).…”
