The compound NH4HCN2 (1) was prepared by the reaction of H2CN2 with liquid ammonia. The ammonium salt 1 was characterized by a low temperature single-crystal X-ray structure analysis. The anionic part of the structure consists of HCN2- anions, which are connected via N-H center dot center dot center dot N bonds (H center dot center dot center dot N distance: 2.47 angstrom, DHA: 165 degrees). The N-H center dot center dot center dot N hydrogen bonds of the ammonium ion to the anions range from 2.00 to 2.14 angstrom (DHA=Donor center dot center dot center dot Acceptor angles: 165-176 degrees), all N-H center dot center dot center dot N interactions together give rise to a three-dimensional network. 1 decomposes quantitatively to dicyandiamide at room temperature.
