In the racemic title compound, C22H21NO3, the nitrogen-containing ring of the pyranoquinoline moiety adopts a slightly distorted half-chair conformation and the oxygen-containing ring adopts a slightly distorted chair conformation. The benzene rings make a dihedral angle of 84.97 (8)°. In the crystal, weak C—H
O interactions link the molecules into chains extending along the a-axis direction.

In the title compound, [Mg(C3H3N2)4(H2O)2]Cl2, the MgII cation lies on a crystallographic inversion centre and is coordinated by two water molecules and four N-atom donors from monodentate imidazole ligands, giving a slightly distorted octahedral stereochemistry. In the crystal, water O—HCl and imidazole N—HCl hydrogen bonds give rise to a three-dimensional structure.
