7-Methoxyindan-1-one
In the title compound, C(10)H(10)O(2), the 1-indanone unit is essentially planar (r.m.s. deviation = 0.028 Å). In the crystal, molecules are linked via C-H⋯O hydrogen bonds, forming layers lying parallel to the ab plane. This two-dimensional structure is stabilized by a weak C-H⋯π inter-action. A second weak C-H⋯π inter-action links the layers, forming a three-dimensional structure.

In the title compound, C(9)H(8)O(2), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The dihedral angle between the mean plane of the S(6) ring and the benzene ring is 1.89 (2)°. In the crystal, inversion-related mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming a cyclic dimers with R(2) (2)(12) graph-set motif. Weak inter-molecular C-H⋯O(carbon-yl) and C-H⋯O(hy-dro...

In the crystal structure of the title compound, C(8)H(5)N(3)O(3), inter-molecular N-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers. These dimers are, in turn, linked though weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds and π-π stacking inter-actions, with centroid-centroid distances of 3.678 (3) Å, into a three-dimensional network.

In the deca-hydro-phenanthrenone ring system of the title compound, C(27)H(44)O, the two cyclo-hexane rings adopt chair conformations, whereas the cyclo-hexene ring adopts an envelope conformation. The cyclo-pentane ring is twisted. In the crystal structure, mol-ecules are stacked along the a axis, but no significant inter-molecular inter-actions are observed.

In the title compound, C(11)H(12)O(2), the six-membered ketone ring fused to the 7-meth-oxy benzene ring adopts a slightly distorted envelope configuration with the central methyl-ene C atom being the flap. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions, which lead to supra-molecular layers in the bc plane.
