Figure 1 The molecular structure of [C18H18N2][HgCl2.75I1.25]. Displacement ellipsoids are drawn at the 50% probability level. Labels X1 and X2 denote the disordered I and Cl atoms (I1, I2, Cl1 and Cl2). Hydrogen atoms are drawn as spheres of arbitrary radius. [Symmetry code (i): 1-x, 1-y, 2-z; (ii) 2-x, −1-y, 2-z.] |
