- Abstract
The synthesis of a Schiff base-appended macrocycle $$[\{\hbox {P}({\mu }\hbox {-}^{t}\hbox {BuN})\}_{2}(\hbox {O}-m-\hbox {C}_{6}\hbox {H}_{4}\hbox {CHNCH}_{2})_{2}]_{2}$$ ( 1) containing cyclodiphosphazane moieties is described. Reactions of 1 with $$\hbox {H}_{2}\hbox {O}_{2}$$ and elemental selenium yielded derivatives tetrakis(oxide) $$[\{\hbox {P(O)}({\mu }\hbox {-}^{t}\hbox {BuN})\}_{2}(\hbox {O}-m-\hbox {C}_{6}\hbox {H}_{4}\hbox {CHNCH}_{2})_{2}]_{2}$$ ( 2) and tetrakis(selenide) $$[\{\hbox {P(Se)}(\mu \hbox {-}^{t}\hbox {BuN})\}_{2}(\hbox {O}-m-\hbox {C}_{6}\hbox {H}_{4}\hbox {CHNCH}_{2})_{2}]_{2}$$ ( 3), in $$\sim $$ 80% yield. Tetragold complex $$[\hbox {Au}_{4}\hbox {Cl}_{4}\{\{\hbox {P}( \mu \hbox {-}^{t}\hbox {BuN})\}_{2}(\hbox {O}-m-\hbox {C}_{6}\hbox {H}_{4}\hbox {CHNCH}_{2})_{2}\}_{2}$$ ] ( 4) was prepared by reacting 1 with [ $$\hbox {AuCl}(\hbox {SMe}_{2})$$ ] in 1:4 molar ratio. All the compounds have been characterized by various spectroscopic techniques. The molecular structure of 3 was confirmed by single crystal X-ray analysis. Graphical Abstract : SYNOPSIS The synthesis of chalcogenides and gold complex of a Schiff base appended cyclodiphosphazane containing macrocycle $$[\{\hbox {P}({\mu }\hbox {-}^{t}\hbox {BuN})\}_{2}(\hbox {O}-m-\hbox {C}_{6}\hbox {H}_{4}\hbox {CHNCH}_{2})_{2}]_{2}$$ is described.
