Design and synthesis of organochalcogen (Se or Te) based multifunctional derivatives: structural determination and dynamic behavior of 2-chloro-4,6- bis(phenylselenoethylamino)-1,3,5-triazines

A novel class of multifunctional and multinucleate chalcogen (selenium and tellurium) containing derivatives (1-10) has been developed based on sequential chloride substitution of 2,4,6-trichloro-1,3,5-triazine with chalcogen-bearing amines. The structure of compound 1 has been determined in the solid state by X-ray crystallography. There is continued interest in the rational design and synthesis of new organic donors with variable donor functionalities and their combinations with metals to build supramolecular structures. Organic donors bearing variable donor functionalities such as O, S, N and P in their structural framework have been studied for several years and continue to be an area of active research for understanding the properties of donors that offer the opportunity to design metal complexes for specific purposes and applications." The interplay between electronic and steric properties of a metal atom has long been recognized but predictions related to the behavior of organic donors remain difficult. The behavior of selenium in organic species remains uncertain. Studies of given systems are required before one could arrive at conclusions about reactivity and applications. The presence of selenium in a given structural motif of an organochalcogen species has a significant influence on the final structure of a complex, especially
