Structural analysis reveals the molecular geometry of an iron dihydrogen complex, highlighting intact hydrogen-hydrogen coordination.

Key Points

Determine the precise solid-state crystal structure and hydrogen bonding geometry of the transition-metal complex trans-[Fe(η2-H2)(H)(PPh2CH2CH2PPh2)2]BPh4.
Conducted single-crystal X-ray diffraction on crystalline samples of trans-[Fe(η2-H2)(H)(PPh2CH2CH2PPh2)2]BPh4.
Performed single-crystal neutron diffraction to accurately resolve the positions of the hydrogen atoms and the coordinated dihydrogen ligand.
Determined the three-dimensional atomic structure of the trans-[Fe(η2-H2)(H)(PPh2CH2CH2PPh2)2]+ cation.
Confirmed the intact side-on coordination mode (η2) of the dihydrogen molecule bound to the iron center.
