The anion of the title salt, 2[C(NH2)3]+·C2N8O22−, 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.

Guanidine carbonate (180 mg, 1 mmol) was added to a methanol solution (10 ml) of 1,1'-dihydroxy-5,5'-bistetrazole (206 mg, 1 mmol). The mixture was stirred for 2 h. The white precipitate that formed was filtered and washed with methanol; yield 0.245 g (90%). CH&N Elemental analysis for C4H8N14O2: Calc. C 16.90, H 2.84, N 69.00%. Found C 16.74, H 2.87, N 68.23%. Diethyl ether was used to recrystallize the compound.
The amino H-atoms were located in a difference Fourier map, and were refined with a distance restraint of N–H 0.88±0.01 Å; their displacement parameters were refined.

The depronated ion of 1,1'-dihydroxy-5,5'-bistetrazole is an example of an organic compound having no hydrogen atoms, and is an appropriate building block for the synthesis of coordination polymers that require metal–nitrogen linkages. To date, no crystal structure of the metal derivatives have been reported. The ion is obtained by the reaction of 1,1'-dihydroxy-5,5'-bistetrazole with guanidine. In the salt (Scheme I), the anion lies on a center of inversion; its two five-membered rings are necessarily coplanar. The guanidinium cation forms N–H···O and N–H···N hydrogen bonds to the anion to generate an eight-membered ring (Fig. 1). Other hydrogen bonds lead to the formation of a three-dimensional network (Table 1).
