Abstract
In the title compound, C(35)H(36)N(2)O(5)center dot 0.5C(4)H(10)O, the asymmetric unit contains one bicyclo[3.3.1]nonane molecule and a half-occupancy diethyl ether solvent with the O atom lying on a crystallographic inversion center. Two intramolecular N-H center dot center dot center dot O hydrogen bonds generate S(6) ring motifs. The bicyclo[3.3.1] nonane ring system adopts a chair-boat conformation. In the crystal structure, the molecules are linked by weak intermolecular C-H center dot center dot center dot N hydrogen bonds into chains along the b axis; additional stabilization is provide by C-H center dot center dot center dot pi interactions.
