title: Crystal structure of (4-chloro-phen-yl)[2-(10-hy-droxy-phenanthren-9-yl)phenanthro[9,10-b]furan-3-yl]methanone.
abstract: In the title compound, C37H21ClO3, the dihedral angle between the two phenanthrene moieties is 57.79 (5)°. The furan and one of the phenanthrene groups are fused in an almost coplanar arrangement [dihedral angle = 5.14 (8)°] and the furan unit makes dihedral angles of 70.27 (11) and 57.58 (8)° with the planes of the phenyl and the second phenanthrene group, respectively. In the crystal, neighbouring mol-ecules are connected via two inter-molecular hydrogen-bonding inter-actions (O-H⋯O and C-H⋯O) towards the carbonyl O atom with donor-acceptor distances of 2.824 (2) and 3.277 (3) Å, creating an inversion dimer. A non-classical C-H⋯Cl inter-action [3.564 (2) Å] and three C-H⋯π inter-actions, with C⋯π distances of 3.709 (3), 3.745 (2) and 3.628 (3) Å, connect the mol-ecules, forming a three-dimensional supra-molecular architecture in the solid state.
