Synthesis and structural characterization of diorganotin(IV) complexes with 2,6‐pyridinedicarboxylic acid

“…The Sn-N bond length, 2.287(4) Å, is very close to that of complex 1, and is similar to the bond length in the other diorganotin complex of 2,6-pyridinedicarboxylic acid. [26] The two O-Sn-N bite angles, 67.50 (12) • and 71.68 (13) • , are similar to those of compound 1 and are non-equivalent. The N1-Sn1-O1w angle, 147.18 (13) • , is the largest angle among angles in the equatorial plane, and indicates the extent of distortion from the ideal geometry.…”

“…[25] Cleavage of the phenyl group has also been observed in the authors' earlier study when potassium isopropoxide and methyldiphenyltin(IV) iodide were used as reagents in synthesis. [26] …”

“…The geometry around the tin atom can best be described as a distorted pentagonal bipyramidal in which the two phenyl groups are trans to each other, defining a C-Sn-C angle of 167.52 (8) • . Two methanol molecules link the aforementioned tin/sodium aggregates into a [13] [MePhSn(2, 6-C 5 H 3 N)(COO) 2 (H 2 O)] 2 [26] and slightly longer than in [EtPhSn(2, 6-C 5 H 3 N)(COO) 2 (H 2 O)] 2 . [31] The hexa-coordinated sodium derivative of 2,6-pyridinedicarboxylic acid, which is connected to the organotin moiety, is also of interest.…”
