| Popis: |
The title compound (systematic name: 6-amino-2-thioxo-2, 3-dihydropyrimidin-1-ium chloride), C4H6N3S+ Cl- has two cations and two anions in the asymmetric unit. The two cations have nearly the same structure. Both are nearly planar, the largest distance from the non-H atoms to the least-squares plane through the six-membered ring atoms being 0.010(2) A. Both Cl- ions serve as hydrogen-bond acceptors. One thiocytosinium cation forms N-H...Cl hydrogen bonds with three Cl- anions and the other one with four Cl- ions, giving a sheet parallel to (101). There is also an N-H...S intermolecular hydrogen bond. |
