2-Imi-niumyl-1,3-diazepane-4-carboxyl-ate.

ABSTRACT: The title compound, C(6)H(11)N(3)O(2), is a cyclized derivative of l-arginine and the mol-ecule is a zwitterion with the positive and negative charge residing in the guanidinium and carboxyl-ate groups, respectively. The conformation of 1,3-diazepane ring is close to a twisted chair. One intra-molecular and three inter-molecular N-H⋯O hydrogen bonds stabilize the mol-ecular conformation and the crystal structure, respectively.
