The synthesis and structural characterization of some triorganotin(IV) complexes of 2-{[(E)-1-(2-hydroxyaryl)alkylidene]amino}acetic acid. Crystal and molecular structures of Ph3Sn(2-OHC6H4C(H)NCH2COO) and Me3Sn(2-OHC6H4C(CH3)NCH2COO)

A novel compound of triphenyltin(IV) with N-tert-butoxycarbonyl-l-ornithine causes cancer cell death by inducing a p53-dependent activation of the mitochondrial pathway of apoptosis

“…, as widely observed in the infrared spectra of triorganotin(IV) carboxylates [26]. A medium intensity band corresponding to the sn-O stretching mode of vibration appears at 447 cm…”

Amino acetate functionalized Schiff base organotin(IV) complexes as anticancer drugs: synthesis, structural characterization, and in vitro cytotoxicity studies

“…in CDCl 3 exhibit a single sharp 119 Sn resonance in the range -83 to -103 ppm, suggesting that the Sn-atoms in the complexes have the same four-coordinate environment [42,47,49,62,63]. This is also reflected in 1 J( 13 C-119/117 Sn) coupling constants (see experimental) and the values are unambiguously characteristic for four-coordinate tin atoms [63].…”

“…In view of the increasing interest in organotin(IV) carboxylates and prompted by their structural diversity [38] and broad therapeutic activity [27], organotin(IV) complexes of Schiff bases derived from amino acids have also been investigated extensively [39][40][41][42][43][44][45][46][47][48][49]. An overview of the coordination behaviour of such Schiff bases towards organotin(IV) is shown in Scheme 1.…”

Synthesis, characterization and crystal structures of 2-[(E)-2-(4-hydroxy-3,5-dimethylphenyl)-1-diazenyl]benzoic acid and its polymeric and monomeric triorganotin(IV) complexes

“…The preference for the formation of the zwitterionic form of the ligand in complexes may be a result of the coordination of the phenoxide O-atom to the Sn-atom in 1 and 2 while a steric reason could be ascribed for 3 where such coordination is absent. However, quinoid or zwitterionic forms are quite commonly encountered in similar systems [25][26][27][28].
