Abstract

The reaction of a three-armed ligand of trimesoyltri(L-alanine) (TMTAH₃) with CuCl₂ gave [Cu₁₂(TMTA)₈(H₂O)₁₂]·8CH₃CH₂OH·40H₂O (1) as expected. It features paddlewheel dinuclear secondary building blocks, six of which are connected by eight TMTA³⁻ linkers, forming a Mo₆C1₈⁴⁺-like dinuclear-based octahedral nanocage. The magnetic studies revealed the presence of antiferromagnetic interactions between the Cu(II) ions in 1. The desolvated sample of 1 presents nice selectivity on the adsorption of H₂ and CO₂ over CH₄.
