چکیده
In the title compound, C(2)H(4)N(6)O, the planar [maximum deviation = 0.006 (2) Å] amino-tetra-zole group makes a dihedral angle of 83.65 (8)° with the formamide unit. In the crystal structure, inter-molecular N-H⋯N, N-H⋯O and C-H⋯N hydrogen bonds are responsible for the formation of a three-dimensional network.

In the mol-ecule of neutral bis-[(1H-tetra-zol-5-yl)meth-yl]nitramide, (I), C4H6N10O2, there are two intra-molecular N-H⋯O hydrogen bonds. In the crystal, N-H⋯N hydrogen bonds link mol-ecules, forming a two-dimensional network parallel to (-201) and weak C-H⋯O, C-H⋯N hydrogen bonds, and inter-molecular π-π stacking completes the three-dimensional network. The anion in the molecular salt, tri-am...

The anion of the title salt, 2[C(NH(2))(3)](+)·C(2)N(8)O(2) (2-), lies on a center of inversion and its two five-membered rings are coplanar. The guanidinium cation forms N-H⋯O and N-H⋯N hydrogen bonds to the anion, generating an eight-membered ring. Other hydrogen bonds lead to the formation of a three-dimensional network.
