Abstract

The title compound, C 46 H 26 N 2 O 7 ·1.5CH 3 CN, is the aldol condensation product of bindone with indazole-3-carbaldehyde followed by double intermolecular cyclization. The asymmetric unit, which has monoclinic P2 1 /c symmetry, contains two independent molecules of the title compound and three acetonitrile molecules. The title molecule comprises a central eight-membered ring, which contains an enol-ester, from which five arms extend. The arms exhibit intermolecular interactions within the crystal lattice between molecules of the title compound and with co-crystallized solvent molecules (acetonitrile).
