The new ligands 2,6-bis[2′-(N,N-dialkylaminomethyl)phenylselanyl}methyl]pyridine with the general formula 2,6-[2′-(R2NCH2)C6H4}SeCH2]2C5H3N [R = Me (L1), Et (L2)], based on pyridine functionalized with organoselenium groups, were obtained by reacting 2-(R2NCH2)C6H4SeNa with 2,6–bis(bromomethyl)pyridine in 2:1 molar ratio. The coordination behaviour of the potentially multidentate ligands was investigated
