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.

The synthesis and room-temperature single-crystal X-ray structural characterization of 25,27- di(allyloxy)-5,17-di-t-butyl-26,28-dimethoxycalix[4]arene are recorded. Crystals are monoclinic, C2/c, a 29.089(5), b 10.742(2), c 26.218(8) Ǻ, β 110.09(2)°, Z = 8; the structure was refined to a residual of 0.065 for 4103 independent 'observed' [I > 3σ(I)] reflections. The flattened partial cone conformation of the molecule allows inclusion of one of the methoxy substituents in a way which could block inclusion of a metal ion capable of polyhapto aromatic coordination and which may therefore explain why solution n.m.r. measurements indicate that silver(I) binds to the pendent alkene groups.
