The aqueous solution reactions of heterometallic cube derivatives of [Mo3S4(H2O9]4+, written here as [Mo3MS4(H2O)10]4+ (tetrahedral M = Fe, Co, Ni, Pd, Cu) with carbon monoxide are considered. Thermodynamically favourable reactions complete in 330 min are detected with M = Co (Group 9), and Ni and Pd (Group 10) containing cubes having 15 and 16 metal electrons, respectively, but no corresponding reactions are observed with M = Fe, Cu cubes having 14 and 17 metal electrons, respectively. A similar reaction is observed with the Se-containing cube [Mo3NiSe4(H2O)10]4+ , and with the higher oxidation state cube [Mo3CuS4(H2O)10]5+ (16 electrons) [Mo3S4(H2O)9]4+ and Cu(CO)+ are obtained as final products. On bubbling N2 through the latter CO is removed, and approaching quantitative reformation of [Mo3CuS4(H2O)10]5+ is observed. Greater difficulty is experienced in removing carbon monoxide from the other carbonyl adducts (M = Co. Ni, Pd) using N2 © 1999 Elsevier Science S.A. All rights reserved.
