Macrocyclic cyclodiphosphazane $$[\{\hbox {P}(\mu \hbox {-}^{t}\hbox {BuN})\}_{2}(\hbox {O}-m-\hbox {C}_{6}\hbox {H}_{4}\hbox {CHNCH}_{2})_{2}]_{2}$$ [ { P ( μ - t BuN ) } 2 ( O - m - C 6 H 4 CHNCH 2 ) 2 ] 2 : synthesis of chalcogen derivatives and gold(I) complex

The synthesis of a Schiff base-appended macrocycle (1) containing cyclodiphosphazane moieties is described. Reactions of 1 with and elemental selenium yielded derivatives tetrakis(oxide) (2) and tetrakis(selenide) (3), in 80% yield. Tetragold complex ] (4) was prepared by reacting 1 with [] 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
