Figure 1
The expanded asymmetric unit of the title crystal structure, showing the naming scheme. The asymmetric unit contains half of each component: dimethylammonium, 4-(dimethylamino)pyridinium, and [PbCl4]2−. Displacement ellipsoids are drawn at the 50% probability level. Atom colors: carbon (gray), nitrogen (blue), hydrogen (white), lead (dark blue) and chlorine (green). [Symmetry operators: ($1) x, 1 − y, − + z; ($2) 2 − x, y, − z; ($3) 2 − x, 1 − y, 1 − z; ($4) 1 − x, y, − z; ($5) 1 − x, y, − z.] |
