Synthesis, characterization and crystal structures of polymeric and dimeric triphenyltin(IV) complexes of 4-(((E)-1-{2-hydroxy-5-((E)-2-(2-carboxyphenyl)-1- diazenyl)phenyl}methylidene)amino)aryls
Tushar S. Basu Baul,Keisham Surjit Singh,Michal Holčapek,Robert Jirásko,Eleonora Rivarola,Anthony Linden +5 more
TL;DR: The triphenyltin(IV) complexes of 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1diazenyl]phenyl}methylidene)amino]aryls (aryls) have been synthesized and characterized by 1H-, 13C-, 119Sn-NMR, ESI mass spectrometry, IR and 119mSn Mossbauer spectroscopic techniques in combination with elemental analysis.
Journal ArticleDOI
Electrospray ionization mass spectrometry of tributyltin(IV) complexes and their larvicidal activity on mosquito larvae: crystal and molecular structure of polymeric (Bu3Sn[O2CC6H4{NN(C6H3‐4‐OH(C(H)NC6H4OCH3‐4))}‐o])n

TL;DR: Toxicity studies of the tributyltin(IV) complexes of the 4]-((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)1-diazenyl]phenyl}methylidene)amino]aryls on the second larval instar of the Aedes aegypti and Anopheles stephensi mosquito larvae are also reported as discussed by the authors.
Journal ArticleDOI
Synthesis of a cyclic dinuclear organotin carboxylate via simultaneous debenzylation and decarbonylation reactions: X-ray crystal structure of [(PhCH2)2{O2CC6H4{N(H)N(C6H3-4(O)-5-O)}-o}Sn]2
TL;DR: In this article, a cyclic centrosymmetric dinuclear moiety linked into extended chains by pairs of long Sn⋯O contacts was identified and their structures differ primarily in the packing arrangement afforded by the benzyl groups.
Journal ArticleDOI
Synthesis, characterization, crystal structures and in vitro antimicrobial activities of triorganotin(IV) complexes of azo-dicarboxylates
TL;DR: Triorganotin(IV) complexes have been synthesized by reacting bis-tri-n-butyltin(IV)-oxide with (E)-5-((2-carboxyphenyl)diazenyl)-2-hydroxy benzoic acid (L1HH′) [compound 1] and tri-organotin (IV) chlorides [R ǫ, Me] with either sodium salt of (E −5-(2-Carboxyphensyl)dazenyl))-2 -hydroxy benzzoic ac
Journal ArticleDOI
Synthesis, characterisation and anti-diabetic activities of triorganotin(IV) azo-carboxylates derived from amino benzoic acids and resorcinol: Crystal structure and topological study of a 48 membered macrocyclic-tetrameric trimethyltin(IV) complex
TL;DR: Triorganotin(IV) complexes of azo-carboxylic acids derived from amino benzoic acids and resorcinol were synthesized by the reaction of 2/4-(2,4-dihydroxy-phenylazo)-benzoic acid with appropriate triorganotin( IV) chlorides [R = Me (1 and 3), Ph (2 and 4) and Bu (5)] in presence of triethylamine as discussed by the authors.
