Abstract The structure of KAuCl4 (1), previously reported in the non-centrosymmetric space groupPc, has been successfully redetermined inP21/c; the gold atoms occupy centers of symmetry. The scatter of chemically equivalent bond lengths is greatly reduced and the precision of bond lengths and angles correspondingly improved. The structure of Cl3PAuCl (2), determined in 1962, has been redetermined to obtain more precise values for molecular dimensions; new values are Au-P 2.198, Au-Cl 2.279(2)Å. Short Au⋯Au contacts (3.081 Å) connect the molecules in chains. The structure of Ph3PSAuCl (3), for which a very long Au-Cl bond (2.555 Å) had been reported, was redetermined and gave a normal Au-Cl bond length of 2.265(2) Å; the previous value was probably a typing error. All redeterminations were carried out at −95°C.
