Spiro[2.4]hepta-4,6-diene was obtained according to the literature procedure (Wilcox et al., 1961). First fraction from the final distillation of spiro[2.4]hepta-4,6-diene (2.05 g) was stored at room temperature for few weeks. After this time large, colorless crystals of the title compound deposited with 54% (1.10 g) yield.
All H atoms were positioned geometrically and refined using a riding model, with C–H = 0.93–0.98 Å, Uiso(H) = 1.2 Ueq(C).

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 a product of cyclodimerization of spiro[2.4]hepta-4,6-diene. After few weeks of storing of the starting diene at room temperature big crystals of (I) were isolated with relatively high yield. In contrast to previously reported method of synthesis of (I) (Khusnutdinov et al. 1988), we did not use the additional heating and the catalyst.
The X-ray crystallographic analysis confirms this proposed molecular structure (Fig. 1). The C14H16 is built up from three five-membered rings and two three-membered rings. The one of the five-membered rings (C2—C3—C4—C5—C6) is almost planar. The mean deviation of the five atoms C2, C3, C4, C5, C6 from their least-squares plane is 0.0136 Å. Additionally, the C5 atom is a junction between the five-membered ring and a cyclopropane ring. The dihedral angle between the central ring planes is 89.89 (2)°.
The second and third five-membered rings (C1—C2—C6—C7—C10 and C7—C8—C9—C1—C10) have an envelope conformation.The C10 atom is a junction with the second cyclopropane ring.
The typical C2=C3 and C6=C7 double bonds lengths 1.312 (3) Å, 1.309 (3) Å respectively suggest that the C2, C3, C6, C7 atoms are sp2 hybridized. The bond lengths and angles are within normal ranges (Brookings et al. 2001; Caira et al. 1995; Haumann et al. 1997).
