Organotin(IV) complexes with tridentate ligandsI. Dimethyltin(IV) complexes with N-salicylidene derivatives of Aroylhydrazines, S-methylhydrazinecarbodithioate and 4-substituted thiosemicarbazides

Synthesis, characterisation and structural aspects of a new diorganotin(IV) complex with N′-(5-bromo-2-hydroxybenzylidene)benzoylhydrazone ligand

“…Recently, the applications of p-block elements as precursors for Metal Organic Chemical Vapour Deposition (MOCVD) synthesis of new electronic materials have come out as an emerging area of interest. Tin(IV) complexes containing (O, O) [1]; (N, O) and (O, S) [2][3][4][5] are most worthy to be mentioned for their excellent activities as fungicides, bacteriocides and anti-inflammatory agents [6][7][8]. A series of organotin(IV) derivatives and a number of diorganotin halides and pseudohalides [SnR 2 × 2 L 2 ] [L = amino ligand, e.g.…”

“…However, very few investigations have been devoted to the diorganotin(IV) complexes derived from benzoic acid hydrazone [6]. In order to facilitate the preparation of these types of diorganotin(IV) complexes, our group has initiated the present study with substituted salicylaldehyde hydrazone ligand.…”

Synthesis, characterization and thermodynamic studies of complexes of dimethyl, diethyl, and diphenyltin(IV) dichlorides with (2H)-1,4-benzothiazine-2,3-(4H)-dione dioxime

“…All these band absorptions were seen in the complexes but some of them shifted with respect to free H 2 L. The stretching vibration of N-O observed at 920 cm -1 in H 2 L is shifted to the higher region at 922-945 cm -1 in the complexes supporting that oxime N atoms are coordinated to Sn(IV). In the 440-480 cm -1 region of infrared spectra of complexes some bands appeared for Sn-N stretching vibration [26]. The intense band observed at 1635 cm -1 in the H 2 L attributed due to imine C=N appears at 1645-1649 cm -1 in the IR spectra of complexes.…”

Synthesis, structural and spectral studies of five- and six-coordinate adducts of organotin(IV) halides containing dibenzylsulfoxide (dbso) as ligand. The crystal structures of fac-[MeSnCl3(dbso)2] and trans-[Ph2SnCl2(dbso)2]

“…The polarity of these bonds depends on the amount of residual positive charge located on tin, as well as on the s-character of tin(IV) in these bonds. 24 Accordingly, more residual positive charge is localized on the central tin(IV) atom in Ph 2 Sn 2+ compared to Me 2 Sn 2+ . Therefore, more shielding is expected on the tin(IV) atom in the five-coordinate diphenyltin(IV) derivative.…”
