Figure 1
The asymmetric unit of 1, chosen to give a compact segment with all n-butyl groups of the hydrophobic layer region oriented in one direction. In addition, the symmetry-related second half of the hexachloridodipallate(II) anion is shown in transparent mode [symmetry code: (i) −x, 1 − y, 1 − z.]. The direction of coordinative bonding to atoms of neighbouring moieties is given by sharpened sticks, and hydrogen bonds are shown as segmented solid bonds. Displacement ellipsoids are drawn at the 50% probability level, hydrogen atoms are drawn with an arbitrary radius. Note the coordination of the hexachloridodipalladate(II) ion to hydrophilic moieties by hydrogen bonding and `local' ionic interactions. |
