• A new benzodiazepine has been synthesized through a Schiff base condensation procedure.
• The organic molecule does not coordinate to diorganotin(IV) moieties.
• Metal–organic helical supramolecular structures are formed via H-bonds involving organometallic and organic cationic species.
2-Methyl-2,4-di-thiophen-2′,2″-yl-2,3-dihydro-1H-benzo[b][1,4]diazepine (L) has been synthesized through condensation of phenylene-1,2-diamine and 2-acetylthiophene, and its reactions with dialkyltin(IV)dichlorides have been studied. Two salts formulated as (LH)[R2SnCl3] (R = Et, 1; R = Me, 2) have been isolated. L and 1 were structurally characterized. The conformation of the benzodiazepine L, changes in 1 due to H-bonds formation. [Et2SnCl3]- is one of the rare examples of five coordinated tin(IV) species and has distorted trigonal bipyramidal geometry. H-bonding interactions, in 1, lead to the formation of supramolecular helices.
