Abstract

Three pentanuclear copper (II) complexes,[Cu 5 (OMe) 2 (CF 3 CO 2)(pehp) 6 (Cl)] 1,[Cu 5 (OMe) 2 (CF 3 CO 2)(pehp) 6 (NO 3)] 2 and [Cu 5 (OH)(CF 3 CO 2) 3 (pehp) 6] 3, have been prepared via the solid-state reaction of hydrated copper (II) nitrate with the sodium salt of the novel ligand, 6-(phenylethynyl)-2-pyridone (Hpehp) in the presence of sodium trifluoroacetate. Crystal structural analysis at 220 K of 1–3 reveals capped-butterfly ...
