Abstract
The newly attempted template synthesis involving 1-hydrazinocarbonylmethyl-7-bromo-5-phenyl-1,2-dihydro-3 H -1,4-benzdiazepin-2-one (Hydazepam - HHy) (1), 2-hydroxy-1-naphtaldehyde (HNf) (2) and tin tetrachloride (3) in the solution of iso -propanol has afforded a tin(IV) coordination compound with 1-[(2-hydroxy-1-naphtyl)methylenhydrazino]carbonylmethyl-7-bromo-5-phenyl-1,2-dihydro-3 H -1,4-benzdiazepin-2-one (H2HyNf) (4) - the product of condensation of 1 with 2. The composition of the complex [Sn(HHyNf)Cl3] (5) and its structure have been confirmed by a number of physical chemical methods. Its molecular structure has been determined by single crystal XRD. The coordination polyhedron of the tin atom is an octahedron formed by three chlorine atoms, azomethine nitrogen atom and two oxygen atoms of the carbonyl and deprotonated hydroxy group of the ligand.
