The crystal structure of 6,7-di-hydro-5-pyrrolo-[1,2-]imidazole, CHN, at 100 K has monoclinic (2/) symmetry. The mol-ecule adopts an envelope conformation of the pyrrolidine ring, which might help for the relief torsion tension. The crystal cohesion is achieved by C-H⋯N hydrogen bonds. Inter-estingly, this fused ring system provides protection of the α-C atom (attached to the non-bridging N atom of the imidazole ring), which provides stability that is of inter-est with respect to electrochemical properties as electrolytes for fuel cells and batteries, and electrodeposition.
6,7-二氢-5-吡咯并-[1,2-]咪唑（CHN）在100 K时的晶体结构具有单斜晶系（2/）对称性。该分子采用吡咯烷环的信封式构象，这可能有助于缓解扭转张力。晶体凝聚通过C-H⋯N氢键实现。有趣的是，这种稠环体系为α-C原子（连接到咪唑环的非桥连N原子）提供了保护，这在作为燃料电池和电池电解质以及电沉积的电化学性质方面提供了具有重要意义的稳定性。
