The title compound, 4,4′-bis[(2,2′:6′,2″- terpyridin-4-yl)ethynyl]-2,2′-(3,6,9-trioxaundecane-1,11-diyldioxy)-1, 1′-biphenylethyl acetate solvate, C54H42N 6O5·C4H8O2, is a sterically constrained ligand based on the well-known chelator 2,2′:6′,2″-terpyridine (terpy). Two terpy units are linked by ethynyl bridges to a central 2,2′-biphenyl unit, in which the two rings are connected by a polyether strand. The torsion angle between the two rings of the biphenyl unit is 113.25 (17)°. The crown ether ring is flexible and capable of complexing metal cations, and the two terpy units may be reorganized from their observed trans-trans configuration to act as terdentate ligands for transition metal ions. © 2004 International Union of Crystallography Printed in Great Britain - all rights reserved.
