Figure 13
A perspective view of (IV), showing the atom-numbering scheme. Part (a) contains the two tautomeric forms of BMIC, while part (b) shows the 6-chloroisocytosine molecule, which is substituted with the 3H tautomeric form of BMIC. In both parts, displacement ellipsoids are drawn at the 50% probability level and hydrogen bonds are indicated as dashed lines. |
