An efficient synthesis and structural aspects of a novel class of selenium bearing hexa-hosts by the reaction of hexafluorobenzene or hexakis (bromomethyl) benzene with RSe− ions is demonstrated. However, under identical reaction conditions, our attempts to prepare tellurium analogues by the reaction of RTe−(R= Ph or p-CH3C6H4-) with hexafluorobenzene or hexakis (bromomethyl) benzene to obtain (RTe) 6C6 and (RTeCH2 ...
