Abstract

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 SeO₃ ²⁻ 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⋯SeO₃ ²⁻ interactions and the Cu²⁺ coordination bonds.
