Abstract

The ligand 4,4′-biquinazoline, 1, forms the complex [Ru(bipy)₂(1)]²⁺ which consists of atropisomeric (Δλ/Λδ) and Δδ/Λλ) pairs of enantiomers but upon spontaneous crystallization, resolution of the major Δλ/Λδ pair occurs to give Δλ and Λδ crystals; although the free ligand is covalently hydrated in aqueous solution the ruthenium complex is not
