Site-differentiated hexanuclear rhenium(III) cyanide clusters [Re (sub)6 Se (sub)8 (PEt (sub)3) (sub)n (CN) (sub)6-n] (super)n-4 (n= 4,5) and kinetics of solvate ligand exchange on the cubic [Re (sub)6 Se (sub)8] (super)2+ core

Research has been conducted on the site-differentiated cyanide-substituted hexanuclear rhenium(III) selenide clusters. The preparation of these complexes has been carried out via the heterogeneous reactions of iodo clusters with AgCN in chloroform and the details are reported.
