aPIP—[Pt2I2(H2NCH2CH2NH2)2]. |
bData for the highest resolution shell in parentheses. |
cRsym(I)=ΣhklΣI∣Ii(hkl)−〈I(hkl)〉∣/ΣhklΣi∣Ii(hkl)∣; for n independent reflections and i observations of a given reflection, where 〈I(hkl)〉=average intensity of the i observations. |
dPhasing power=∣FH,calc∣/Σhkl∣∣FPH±FP∣−∣FPH,calc∣∣. |
eAlthough the anomalous signals were weak, they were included in phasing and visibly improved the electron density. |
fRCullis=Σhkl∣∣FPH±FP∣−∣FPH,calc∣∣/Σhkl∣FPH−FP∣. |
gFOM=mean figure of merit=〈cos(αbest−αcalc)〉, where α=phase angle. |
hR=Σhkl∣∣Fobs∣−∣Fcalc∣∣/Σhkl∣Fobs∣, where Rwork=hkl∉T; Rfree=hkl∈T; Rall=all reflections; T=test set. |
