The title compound, (I), was prepared by a literature method (Kelly & Sykes, 1968). The crystals were obtained by dissolving (I) (1.0 g, 2.5 mmol) in methanol (50 ml), and evaporating the solvent slowly at room temperature for about 15 d.
H atoms were positioned geometrically, with C—H = 0.93, 0.98, 0.96 and 0.97 Å for aromatic, methine, methyl and methylene H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 methyl H, and x = 1.2 for all other H atoms.
The title compound, (I), is an intermediate product of drospirenone, which is a new oral contraceptive (Mohr & Nickisch, 2005). We report herein its crystal structure.
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987).
Rings A (C4—C9), B (C7/C8/C10—C13) and C (C10/C11/C14—C17) are not planar, having total puckering amplitudes, QT, of 0.547 (3), 0.477 (2) and 0.676 (3) Å, respectively, and chair, flattened boat and chair conformations, respectively [φ = -173.98 (3)°, θ = 169.83 (3)°; φ = -16.01 (2)°, θ = 115.71 (3)° and φ = -147.03 (3)°, θ = 86.92 (3)°, respectively] (Cremer & Pople, 1975). Rings D (C16/C17/C19—C21) and E (O3/O4/C19/C24/C25) have envelope conformations with atoms C16 and C19 displaced by 0.646 (3) Å and 0.220 (2) Å from the planes of the other four ring atoms, respectively. Rings D and E have pseudo twofold axis and pseudo mirror plane, respectively, running through atom C20 and midpoint of C16—C17 bond (for ring D) and atom C19 and midpoint of C24—C25 bond (for ring E), as can be deduced from the torsion angles (Table 1).
The intramolecular C—H···O hydrogen bonds (Table 2, Fig. 1) result in the formation of three more five-membered rings F (O1/O2/C3/C4/H4A), G (C15/C16/C19/O4/H15A) and H (O3/C16/C19/C23/H23B), in which they may be effective in the stabilization of the structure.
As can be seen from the packing diagram (Fig. 2), the molecules of (I) are elongated along the c axis, and stacked along the a axis. Dipole-dipole and van der Waals interactions may be effective in the molecular packing.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound, (I), is an intermediate product of drospirenone, which is a new oral contraceptive (Mohr & Nickisch, 2005). We report herein its crystal structure.
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987).
Rings A (C4—C9), B (C7/C8/C10—C13) and C (C10/C11/C14—C17) are not planar, having total puckering amplitudes, QT, of 0.547 (3), 0.477 (2) and 0.676 (3) Å, respectively, and chair, flattened boat and chair conformations, respectively [φ = -173.98 (3)°, θ = 169.83 (3)°; φ = -16.01 (2)°, θ = 115.71 (3)° and φ = -147.03 (3)°, θ = 86.92 (3)°, respectively] (Cremer & Pople, 1975). Rings D (C16/C17/C19—C21) and E (O3/O4/C19/C24/C25) have envelope conformations with atoms C16 and C19 displaced by 0.646 (3) Å and 0.220 (2) Å from the planes of the other four ring atoms, respectively. Rings D and E have pseudo twofold axis and pseudo mirror plane, respectively, running through atom C20 and midpoint of C16—C17 bond (for ring D) and atom C19 and midpoint of C24—C25 bond (for ring E), as can be deduced from the torsion angles (Table 1).
The intramolecular C—H···O hydrogen bonds (Table 2, Fig. 1) result in the formation of three more five-membered rings F (O1/O2/C3/C4/H4A), G (C15/C16/C19/O4/H15A) and H (O3/C16/C19/C23/H23B), in which they may be effective in the stabilization of the structure.
As can be seen from the packing diagram (Fig. 2), the molecules of (I) are elongated along the c axis, and stacked along the a axis. Dipole-dipole and van der Waals interactions may be effective in the molecular packing.
