Abstract

The reaction of Pr(NO3)3·6H2O with the ligand 2-hydroxy-N-(2′-hydroxyethyl)-3-methoxybenzamide (H3L) in MeOH–MeCN generates the nonanuclear compound [Pr9(H2L)8(OH)10(NO3)8](NO3)(H2O)2(CH3CN) (1), whose single-crystal X-ray structure reveals the presence of metallacalix[4]arene cavities that host guest molecules. The crystal packing of the antiferromagnetic Pr9 cluster shows an intricate network of hydrogen bonds producing a one-dimensional supramolecular chain.
