Crystallographic data and refinement statistics for pilotin.

aThe parameter values for the range 1.85–1.76 Å and 3.06–2.90 Å are given in parentheses for native and heavy metal derivative data, respectively.
bRmerge = Σhkl Σi|Ii−|/_Σhkl ΣIi, where Ii is the intensity of the ith observation, is the mean intensity of the reflection, and the summations extend over all unique reflections (hkl) and all equivalents (i), respectively.
cRpim = Σhkl [n/(n−1)]1/2 Σi|Ii(hkl)−|/Σhkl Σi Ii(hkl), where n is the multiplicity, other variables as defined for Rmerge[46].
dMSAN is the Mid slope of Anomalous normal probability.
eR-factor = Σhkl|Fo−Fc|/Σhkl Fo, where Fo and Fc represent the observed and calculated structure factors, respectively. The R-Factor is calculated using 95% of the data included in refinement and R-free the 5% excluded.
