Synthesis, characterization and crystal structures of triorganotin(IV) complexes of 4‐[(E)‐2‐(3‐formyl‐4‐ hydroxyphenyl)‐1‐diazenyl]‐ and 4‐{(E)‐4‐hydroxy‐3‐[(E)‐4‐(aryl)iminomethyl]phenyldiazenyl}‐benzoic acids and toxicity studies of their tri‐n‐butyltin(IV) derivatives on the Aedes aegypti and Anopheles stephensi mosquito larvae

Triorganotin(IV) complexes of 4‐[( E )‐2‐(3‐formyl‐4‐hydroxyphenyl)‐1‐diazenyl]‐ and 4‐{( E )‐4‐hydroxy‐3‐[( E )‐4‐(aryl)iminomethyl]phenyldiazenyl}‐benzoic acids (aryls = 4‐CH 3 , 4‐Br, 4‐Cl, 4‐OCH 3 ) have been synthesized. The structures have been characterized by 1 H, 13 C, 119 Sn NMR, IR and 119m Sn Mössbauer spectroscopies. The crystal structures of Ph 3 Sn[O 2 CC 6 H 4 {NN(C 6 H 3 ‐4‐OH[C(H)NC 6 H 4 CH 3 ‐4])}‐ p ] and n Bu 3 Sn[O 2 CC...
