Figure 14
The packing of (py)AuCl3 (Adams & Strähle, 1982), showing two adjacent ladder-like double chains parallel to the b axis at (x, z) = (0.25, 0) and (0.75, 0.5). The view direction is approximately parallel to the c axis (but rotated slightly to reduce overlap). Thick dashed lines indicate Au⋯Cl contacts; thin dashed lines indicate `weak' H⋯Cl hydrogen bonds or short Cl⋯Cl contacts. Atomic coordinates were taken from the database (refcode PYAUCL10); hydrogen-atom positions were calculated using the HADD option of XP (Bruker, 1998). Colour codes for this Figure and for Figs. 29–34 are the same as for those of 1–8 (C and H black, N dark blue, Au yellow, Cl green, Br brick-red), but we do not number the atoms in these Figures because the database numbering is not consistent e.g. for cis and trans halogen atoms. |
