Organotin(iv) Complexes of Schiff Bases: A Review

Self‐Assembly of Organotin(IV) Moieties with the Schiff‐Base Ligands Pyruvic Acid Isonicotinyl Hydrazone and Pyruvic Acid Salicylhydrazone: Synthesis, Characterization, and Crystal Structures of Monomeric or Polymeric Complexes

“…The Sn2-O1#2 (x, y + 1, z) distance [2.745(10) Å] is longer than that of Sn1-O1 [2.340(10) Å], but is comparable with those found in related seven-coordinate diorganotin systems. [20,23] The structure of this complex can therefore be described as a dimer, and the coordination geometry of tin can be also described as a trans-C 2 SnO 4 held together by hydrogen bonds (O4···N6#3 and O8···N3#4). These hydrogen bonds contribute to the crystal stability and compactness and result in a one-dimensional chain arrangement.…”

“…[1][2][3][4] Organotin() complexes with Schiff bases have received increasing attention owing to their antitumor activities and potential applications in biotechnology. [5][6][7][8][9][10][11] In addition, Schiff base organotin() complexes are of interest for structural reasons.…”

Penta- and heptacoordinated tin(IV) compounds derived from pyridine Schiff bases and 2-pyridine carboxylate: Synthesis and structural characterization

“…It has been reported that seven coordinated tin complexes exhibit higher activity towards some cancer cell lines when the 2,6-pyridine carboxylate moiety is part of the molecule [45]. Other studies have focused on the structural aspects of the hypervalent species of the Schiff-based organotin complexes [46][47][48]. These class of compounds are important due to their biological and catalytic applications.…”

Heptacoordinate Tin(IV) Compounds Derived from Pyridine Schiff Bases: Synthesis, Characterization, in Vitro Cytotoxicity, Anti-inflammatory and Antioxidant Activity

“…21,22) The Schiff base-organotin complexes have received special attention in view of their chemistry and structural aspects of hypervalent species. [23][24][25][26][27][28][29][30] Regarding this, investigations concerning chelating properties and coordinative effects of 2,6-diacetylpyridine and its influence on the conformation and geometry of heptacoordinated tin complexes derived of hydrazones, 31,32) semicarbazones, thiosemicarbazones, [33][34][35][36][37][38][39][40] acylhydrazones, 41) have been undertaken. Our interest in organotin(IV) and organosilicon compounds containing pyridine moieties let us to study the influence and nature of the ligand substituents in the formation of pentacoordinate tin and silicon derivatives.…”
