The distances between atoms in the N binding site of the crystals grown in NaBr conditions. (a) The Cu Kα data set and (b) the I04 Diamond data set. (a) The Pt—N bond distance is 2.5 ± 0.6 Å, the Pt—Br distance is 2.4 ± 0.5 Å and the Br to NH distance is 3.6 ± 0.4 Å. (b) The Pt—N bond distance is 2.6 ± 0.1 Å, the Pt—Br distance is 2.5 ± 0.1 Å and the Br to NH distance is 3.5 ± 0.1 Å. The sigmas given on the bond distances, which were unrestrained, were calculated using the Cruickshank DPI values (Cruickshank, 1999BB8). The distance between the Br atom and the NH group of Ile88 is a typical halide hydrogen-bond distance. The Pt atom is shown in grey, the Br atom in yellow, C atoms are in green, O atoms are in red and N atoms are in blue.
