title: 9-Meth-oxy-9-(2-meth-oxy-phen-yl)-9H-xanthene.
abstract: In the title compound, C(21)H(18)O(3), the xanthene system and the meth-oxy-phenyl ring are practically orthogonal with a dihedral angle between their mean planes of 89.27 (3)°. The meth-oxy group attached to the phenyl ring makes a C-O-C-C torsion angle of 11.56 (18)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions into chains along [010]. Weak C-H⋯π inter-actions also occur.
