Hydro­gen-bonded chains in 5-methyl-2-tri­fluoro­methyl-1,2,4-triazolo­[1,5-a]­pyrimidin-7(4H)-one and hydrogen-bonded chains of rings in 5-amino-3-tri­fluoro­methyl-1H-1,2,4-triazole–5-methyl-2-tri­fluoro­methyl-1,2,4-triazolo­[1,5-a]­pyrimidin-7(4H)-one (1/1), the co-crystal of a reaction product and one of its precursors

Figure 5
Part of the crystal structure of (III

) (Borbulevych et al., 1998

), showing the formation of a chain of rings along [010]. The original atomic coordinates and atom-labelling scheme have been used. Atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions (−x, $[{1 \over 2}]$ + y, $[{1 \over 2}]$ − z), (x, 1 + y, z) and (−x, y − $[{1 \over 2}]$ , $[{1 \over 2}]$ − z), respectively.
