HCl , taken from a neutron diffraction study.
Neutron diffraction is similar to X-ray diffraction, but is better able to locate hydrogen atoms.
A molecule, the structure of which was determined by X-ray crystallography. The compound was made in an attempt to model the spectroscopic and reactivity properties of an iron-containing enzyme called nitrile hydratase. The crystal packing for the same molecule. The iron site of nitrile hydratase , the above-mentioned enzyme. The hydrogen atoms are omitted for clarity.
