Diaminopyrimidinium squarate 1 394 hydrate

İngilizce (OpenAlex)

In the title compound, 2C4H5N3+·C4O42−·1.394H2O, both the squarate and the amino­pyrimidinium mol­ecules lie on a crystallographic mirror plane and the water mol­ecules are located between the mirror planes. The inversion-related amino­pyrimidine mol­ecules are linked through N—H⋯N hydrogen bonds [N⋯N = 2.975 (3) Å] to form dimers. The dimers and the squarate dianions are alternately arranged and linked via N—H⋯O hydrogen bonds [N⋯O = 2.621 (2) and 2.811 (2) Å] to form a chain along the c axis. Chains lying on the adjacent planes are linked via O—H⋯O hydrogen bonds [O⋯O = 2.713 (2) Å] involving the water mol­ecules to form a three-dimensional network.
