Valence-induced assembly of CuI–CuII ions into different discrete coordination architectures by a disk-shaped polypyridyl ligand

Abstract

The valences of metal ions were found to play key roles in controlling the formation and structures of discrete coordination architectures in a copper and disk-shaped hexa-monodentate ligand system. When Cu^I and Cu^II ions react with a polydentate ligand HPDQ, a hexanuclear “double-decker” like discrete “LM₃M₃L” coordination architecture (CuI)₆(HPDQ)₂(CHCl₃)₈ (complex 1), and a “LM₃L + LM₃” composite structure complex (Cu(NO₃)₂)₆(HPDQ)₃ (complex 2) are formed, respectively.
