A perspective view of (V), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level. Dashed lines indicate hydrogen bonds. Suffixes `A' refer to the neutral MTU molecule, `B' to the 6-methyl-2-thiouracilate ion, `C' to the 2,4,6-triaminopyrimidinium ion and `X' and `Y' to the two DMF molecules. |
