Octahedral chalcogenide rhenium cluster complexes with imidazole

摘要

Reactions of [{Re(6)Q(8)}Br-6](4-/3-) (Q = S, Se) with molten imidazole lead to the formation of two new neutral cluster complexes [{Re(6)Q(8)}(imzH)(4)(imz)(2)] (imzH = imidazole). The interaction of [{Re(6)Q(8)}(imzH)(4)(imz)(2)] with hydrohalic acids resulted in cationic complexes [{Re(6)Q(8)}(imzH)(6)]X-2 (X = Cl, Br). All compounds were characterised by X-ray single-crystal and powder diffraction analyses, elemental analysis, energy dispersive X-ray and IR spectroscopies. The luminescence of the neutral compounds [(Re(6)Q(8))(imzH)(4)(imz)(2)] was also studied. (C) 2019 Elsevier Ltd. All rights reserved.
