Reported herein are a pair of supramolecular pseudo-isomers, namely, (Cu 3I 3)(Cu 3L 3) 2· H 2O (1) and (Cu 3I 3)(Cu 3L 3) 2 (2) (L = 3-(4-pyridyl)-5-isobutyl-pyrazolate), both of which incorporate Cu 3Pz 3 (Pz = pyrazolate) and Cu 3I 3 clusters as luminophores. The two complexes show distinct yello...
