Popis: The tripodal ligand L forms a trinuclear assembly [L2Cu3]6+ in which large and unsymmetrical anions are encapsulated, with the X-ray structures of [L2Cu3(SeO4)]4+ and [L2Cu3(S2O3)]4+ reported. In the presence of the trigonal pyramidal SeO32− anion, both a trinuclear [L2Cu3(SeO3)]4+ and an octametallic assembly [L4Cu8(SeO3)4]8+ are formed and are analysed by X-ray crystallography. The formation of the octanuclear species is a consequence of maximising both the –NH⋯SeO32− interactions and the Cu2+ coordination bonds.
