This paper outlines the discovery of a newly characterised isomorph of ferrous chloride tetrahydrate, Fe(H2O)6·FeCl4(H2O)2, which was initially identified by X-ray crystallography and confirmed by Mossbauer spectroscopy. The X-ray analysis identifie

Hydrogen transfer is a major channel in the ionized C2H2+/H2CO and H2CO+/C2H2 reaction systems, producing C2H4+ + CO. Similarly, H2 transfer from H2CO is observed in reactions of the ions C3H3+ (linear), CH3CCH+, H2CCCH2+, C3H5+, and HCCCCH+ with for
