title: 4-Morpholine-carboxamidine.
abstract: In the crystal structure of the title compound, C(5)H(11)N(3)O, the C=N and C-N bond lengths in the CN(3) unit are 1.2971 (14), 1.3595 (14) (NH(2)) and 1.3902 (13) Å, indicating double- and single-bond character, respectively. The N-C-N angles are 115.49 (9)°, 119.68 (10)° and 124.83 (10)°, showing a deviation of the CN(3) plane from an ideal trigonal-planar geometry. The morpholine ring is in a chair conformation. In the crystal, the mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds, generating a three-dimensional network.
