Abstract

The structure of [(As₂(NCy)₄}₂Cu₄] reveals a dramatic change in the metal coordination mode compared to that found in the Sb analogue [(Sb₂(NCy)₄}₂Cu₄], resulting in the distortion of the Cu₄ core from a square-planar to a butterfly shape and providing the first illustration of ligand-selective cage modification in such heterobimetallic species; in contrast the square-planar Na₄ arrangement found in [{Sb₂(NCy)₄}₂M₄] (M = Na, Cu, Ag) is retained in [(As₂(NCy)₄}₂Na₄].
