Solid mercury dihydride: mercurophilic bonding in molecular HgH(2) polymers.
Atomic mercury subjected to mercury arc irradiation reacts in solid hydrogen to give the linear HgH(2) molecule with strong IR absorptions at 1902 and 773 cm(-1). Annealing leads to HgH(2) dimer and trimer, and warming above 7 K allows the hydrogen matrix to sublime and solid HgH(2) to form. This covalent molecular solid is characterized by strong IR absorptions at 1802 and 673 cm(-1) and by decomposition at 150-170 K.
