Rizwan, Muhammad published the artcileSynthesis, characterization, HOMO-LUMO study, and antimicrobial activity of organotin(IV) complexes of 4-piperidine carboxamide and its Schiff base, HPLC of Formula: 39546-32-2, the publication is Journal of Coordination Chemistry (2014), 67(2), 341-351, database is CAplus.
A series of organotin(IV) complexes has been synthesized by reacting 4-piperidine carboxamide with CS2 and R2SnCl2/R3SnCl in 1 : 1 M/L ratio at room temperature The synthesized complexes were further treated with benzaldehyde to synthesize Schiff bases under stirring. All the complexes were characterized by elemental anal., FT-IR, 1H and 13C NMR. FT-IR and semi-empirical study confirm the bidentate nature of ligand. The complexes exhibit four-coordinate geometry in solution Thermodn. parameters and mol. descriptors were calculated by using semi-empirical PM3 method. HOMO-LUMO calculations show that chlorodiorganotin complexes are more susceptible to nucleophilic attack when compared with triorganotin complexes. Neg. heats of formation at 298 K demonstrate that , and are thermodynamically stable. The antimicrobial results have shown that complexes containing Schiff base exhibit significantly better activity compared to complexes with carboxamide derivatives
