Restriction of the environment of the dimethylthallium(III) ion by ‘threading’ through a crown ether: X-ray crystal structure of dimethyl(dibenzo[b,k][1,4,7,10,13,16]hexaoxacyclo-octadecin)thallium(III)2,4,6-trinitrophenolate

Abstract

The X-ray crystal structure of the title compound shows that the linear dimethylthallium(III) ion is threaded through the crown ether, with the TlC₂unit held perpendicularly to the plane containing the six ether oxygen atoms and the thallium atom.
