The hydrogensulfato-carbonyl derivative [Cu(CO)-(SO4H)](n), as obtained from the Cu2O/H2SO4/CO system and recrystallized from H2SO4/(CH3O)(2)SO2 has been shown to possess a crystal structure organised in infinite chains built up by corner sharing of CuO3(CO)} and S(OH)O-3} 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).
