Eleven complexes of a hybrid ligand 4â²-(4â´-benzo-15-crown-5)-methyloxy-2,2â²:6â²,2â³-terpyridine (L) were synthesized and characterised by elemental analysis, IR-spectroscopy and X-ray analysis. The crystal structures of seven complexes were determined either from single-crystal data ([NaNCS·L] (6) and [CuL2·NaNCS·Na(NCS)2]+·NCSâ·CH3CN (11)) or from powder diffraction data ([CoL2]2+·2NCSâ (5) and [ML2]2+·2PF6â·nEtOH·mH2O, M = Ni(II) (1), Co(II) (2), Cu(II) (3), Zn(II) (4)) and revealed good coordinating properties of the ligand L and structural diversity of the obtained compounds. In compounds 1â5, the ÏâÏ interactions between pyridine rings or between pyridine and benzene rings play an important role in association of the cations.
