New trans-[Re6S8(CN)(4)L-2] (n-) Rhenium Cluster Complexes: Syntheses, Crystal Structures and Properties

摘要

Reaction of polymeric compound Cs-4[Re6S8(CN)(4)S-2/2] with aqueous solution of KOH led to formation of trans-[Re6S8(CN)(4)(OH)(2)](4-) anion which was crystallized in ordered Cs1.68K2.32[Re6S8(CN)(4)(OH)(2)] center dot A 2H(2)O (1a) and disordered Cs1.83K2.17[Re6S8(CN)(4)(OH)(2)] center dot A 2H(2)O (1b) modifications. The presence of two types of apical ligands, inert cyanides and labile hydroxides, opened a way to other trans-[Re6S8(CN)(4)L-2] (n-) rhenium cluster complexes: trans-[Re6S8(CN)(4)Cl-2](4-), trans-[Re6S8(CN)(4)(H2O)Br](3-), and trans-[Re6S8(CN)(4)Br-2](4-), crystallized as Cs1.84K1.16(H)[Re6S8(CN)(4)Cl-2] (2), Cs1.68K1.32[Re6S8(CN)(4)(H2O)Br] (3), (Me4N)(3)(H5O2)[Re6S8(CN)(4)Br-2] (4), and CsK{Cu(H2O)(2)[Re6S8(CN)(4)Cl-2]} center dot A 4H(2)O (5) salts.
