Synthesis and crystal structure of a wheel-shaped supramolecular coordination complex

Abstract

Supramolecular coordination complex (SCC) possessing spatially arranged three anthraquinone dimers in a slipped-cofacial orientation was achieved by the treatment of Re2(CO)10, 2-hydroxymethylanthraquinone and tritopic N-donor via fac-Re(CO)3-directed one pot approach. The off-set π-stacking and C'O···H bonding interactions stabilize the ring structure. [Figure not available: see fulltext.]
