Assembly of a M4L4 “folded-cube” using a T-shaped, right-angled ligand

A new bipyridine ligand based on a T-shaped 2,4,7-trisubstituted benzimidazole framework was synthesised. When combined with [Pt(dppp)]²⁺ corners, eight right angles (four metal and four ligand) combine to form a M₄L₄ cluster with an unusual folded-cube structure.
