title: The 2:1 salt-type adduct formed between 6-amino-3-methyl-5-nitrosopyrimidine-2,4(1H,3H)-dione and piperidine: sheets containing 20 independent hydrogen bonds.
abstract: The title compound, piperidinium 6-amino-3-methyl-5-nitroso-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-1-ide 6-amino-3-methyl-5-nitrosopyrimidine-2,4(1H,3H)-dione, C(5)H(12)N(+).C(5)H(5)N(4)O(3)(-).C(5)H(6)N(4)O(3), (I), crystallizes with Z' = 2 in the space group P1. There is an intramolecular N-H...O hydrogen bond in each pyrimidine unit and within the selected asymmetric unit the six independent components are linked by 11 hydrogen bonds, seven of the N-H...O type and four of the N-H...N type. These six-component aggregates are linked into sheets by five further hydrogen bonds, three of the N-H...O type and one each of the N-H...N and C-H...O types.
