title: exo-4-[(1H-Benzimidazol-2-yl)meth-yl]-10-oxa-4-aza-tricyclo-[5.2.1.0]decane-3,5-dione.
abstract: In the title compound, C(16)H(15)N(3)O(3), the dihedral angle between the approximately planar benzimidazolyl group (r.m.s. deviation = 0.010 Å) and the pyrrolidine ring is 78.20 (6)°. The C-C-N bond angle of the bridging CH(2) group is 112.14 (16)°. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming infinite chains parallel to [101] and [10[Formula: see text]].
