Rates for associative substitution of this compound in metal aquo complexes gave evidence for a pre-equilibrium step in the Eigen–Wilkins mechanism. Ligands of this compound coordinated to two pyridine-bridged ruthenium centers form a classic mixed-valence complex isolated by Carol Creutz and Henry Taube. (10[1])This compound causes mercury(I) (“mercury-one”) chloride to disproportionate into a black solution, hence the name “calomel.” Planctomycetota (-5[2])bacteria anaerobically oxidize this compound (10[1])into hydrazine, (-5[1])which (-5[1])can also be done (-5[1])by the Olin–Raschig (10[3])process. (10[4]-5[2])The first maser (10[1])was built with this compound (10[5])due (10[1])to its low barrier for umbrella inversion. (10[3]-5[1])This is the (10[1])lightest (-5[1])trigonal pyramidal (10[4])compound. (10[5])For 10 points, (10[1]-5[1])the Haber–Bosch (10[3])process (10[5])generates (10[7]-5[1])what compound (10[6]-5[1])with (10[1])formula (10[2])NH3? ■END■ (10[9]0[1])
