| Abstract: | The hydrogensulfato‐carbonyl derivative [Cu(CO)(SO4H)]n, as obtained from the Cu2O/ H2SO4/CO system and recrystallized from H2SO4/(CH3O)2SO2 has been shown to possess a crystal structure organised in infinite chains built up by corner sharing of {CuO3(CO)} and {S(OH)O3} tetrahedra. The chains are connected by hydrogen bonds in layers, with CO groups leaning out on both sides. The absorption of CO by CuSO4/Cu or by Cu2O in sulfuric acid was quantified as a function of concentration. The CuSO4/Cu system in water absorbs carbon monoxide (CO/Cu molar ratio = 1.0). |
