Abstract The structural characterization of the newly synthesized trinitrato(terpyridine)lanthanoid complexes [Nd(NO3)3(pytpy)(H2O)] (1), [Eu(NO3)3(pytpy)(EtOH)]·EtOH (2·EtOH) and [Tb(NO3)3(ptpy)(EtOH)] (3), with the modified terpyridine ligands pytpy = 4′-(pyridin-3-yl)-2,2′:6′,2″-terpyridine and ptpy = 4′-phenyl-2,2′:6′,2″-terpyridine, show all a coordination number of 10 at the metal ion with three bidentate nitrato ligands and an additional solvent ligand. The coordination polyhedra around the metal ions are highly irregular. Hirshfeld surface analyses of the intermolecular interactions show (C/O–)H⋯O bonding having the largest percentage contribution in all three structures, while there are remarkably few π-π interactions despite the numerous aryl rings.
