Figure 3
2-Methyl-1,3-cyclohexanedione molecule at 123, 220 and 293 K viewed along [010] in the crystal. In the drawing of the molecule at 293 K only one set of disordered methylene groups, C(4) and C(5), have been indicated for clarity, while the other set can be generated by the (vertical) mirror plane Cs comprising all the other non-H atoms of the molecule; this drawing also shows the disorder of methyl C(7)H3, for which clearly two sets of H positions with half occupancies have been found in maps. |
