This compound is unstable (although not as much as [[1.1.1-Propellane|[1.1.1]propellane]]; however it is less persistent than [1.1.1]propellane). The bond angles on the shared carbons are considerably strained: three of them are close to 90°, the other three to 120°. The strain energy is estimated to be 93 kcal/mol (390 kJ/mol).
