| Abstract: | 1-emthylimidazoline-2(3H)-thione (mimtH) reacts with copper(II) sulphate pentahydrate in aqueous acetone to produce the dinuclear complex, Cu2(mimtH)5SO4 · 3H2O; the formula has been established by a combination of chemical and thermal analysis. The monoclinic crystals, (space group Pc, Z = 2), contain dinuclear cations, sulphate ions and water molecules. The dinuclear cation, Cu2(mimtH)52+, consists of two trigonal copper(I) atoms, four terminal, monodentate, S-donating mimtH molecules and one S-bridging (μ2) mimtH molecule. Some average dimensions are:Cu---S, 2.258 Å and S---Cu---S, 120.0°; the Cu---S---Cu bridging angle is 94.8° and the Cu---Cu separation distance is 3.308 Å. |
