Figure 3
Complex rhenium tetranuclear species [Re4(μ3-OH)4(CO)12] at Leu129A, shown as a standard (top) and as a stereo image (bottom). A monomer CIF ligand QEB that was utilized as minimal density is present for the CO ligands and, therefore, they have been omitted. Blue shows the 2Fo − Fc electron-density map contoured at 1.2 r.m.s., green shows the Fo − Fc electron-density map contoured at 5.0σ (the COOT default; Emsley & Cowtan, 2004BB17) and orange shows the anomalous electron-density map contoured at 3.0σ. This figure was prepared using CCP4mg (McNicholas et al., 2011BB998). The weak anomalous peak at the bottom position for a rhenium is indicative of this being an intermediate at the 1 year time point.
