Two Isomers of Iridium Hydride Complex (IMAGE) DOE/Brookhaven National Laboratory Caption The Brookhaven research on an iridium hydride complex revealed two isomers -- different molecular arrangements of the same atoms (represented here with stick figures and the corresponding images showing the positions of the atoms). A simple flip in positioning of the two connected rings of atoms at the bottom of these images relative to the rest of the molecule has a dramatic effect on the respective molecules' properties.
