Abstract

An organotin carboxylate based on amide

Self‐assembly of triorganotin(IV) moiety with 1,2,4,5‐benzenetetracarboxylic acid: Syntheses, characterizations, and influence of solvent on the molecular structure (II)

“…The distorted geometry can be proved by the related C–Sn–C angles [105.9(2)‐117.3(2)°] and O–Sn–C angles [96.0(2)‐113.41(18)°]. These angles and the Sn–C bond lengths [2.088(6)‐2.144(5) Å] are all similar to those found in other triphenyltin carboxylates and complexes 1‐3 reported before . Strong chemical coordinating bonds between carboxylate oxygen and tin atoms are evidenced by the Sn–O bond lengths [Sn(1)‐O(1): 2.064(4) and Sn(2)‐O(3): 2.073(4) Å] which lie in the range of Sn–O covalent bond length .…”

[16] Except that, the distances of Sn(1)···O(2) (2.710 Å) and Sn(2)···O(4) (2.753 Å) although longer than the Sn-O covalent bond length are in the range of intramolecular Sn-O bond length of 2.61-3.02 Å.…”

Organotin Carboxylates based on 3‐(1,3‐Dioxo‐2,3‐dihydro‐1H‐phenalen‐2‐yl)benzoic Acid and the Influence of Solvent on the Molecular Structure

“…The signals for carbon protons of aromatic rings present peaks at 138.94–118.91 ppm, and butyl groups present four peaks at 35.18, 29.64, 25.94, and 12.18 ppm. Single resonances at 173.54 and 169.48 ppm are attributed to COO and C=O groups, respectively . With the coupling constant 1 J ( 119 Sn‐ 13 C) (969 Hz) in solution based on crystal structure data, the C–Sn–C angle in the range of 123.66–151.49° was calculated by the related equation , .…”

New Phosphinato Organo- And Halotin(iv) Derivatives, Adducts and Complexes: Synthesis and Spectroscopic Study

“…Many research groups have been involved in the search of new molecules belonging to organo-and halotin (IV) families because of the various applications found for several molecules of these families [1][2][3][4][5][6]. In the continuation of our work in this field since many years, we have synthesized new phosphinato compounds from Me4NH2PO2 .…”
