Abstract

Reaction of polymeric compound Cs4[Re6S 8(CN)4S2/2] with aqueous solution of KOH led to formation of trans-[Re6S8(CN)4(OH) 2]4- anion which was crystallized in ordered Cs 1.68K2.32[Re6S8(CN) 4(OH)2] • 2H2O (1a) and disordered Cs 1.83K2.17[Re6S8(CN) 4(OH)2] • 2H2O (1b) modifications. The presence of two types of apical ligands, inert cyanides and labile hydroxides, opened a way to other trans-[Re6S8(CN)4L 2] n- rhenium cluster complexes: trans-[Re 6S8(CN)4Cl2]4-, trans-[Re6S8(CN)4(H2O)Br] 3-, and trans-[Re6S8(CN)4Br 2]4-, crystallized as Cs1.84K 1.16(H)[Re6S8(CN)4Cl2] (2), Cs1.68K1.32[Re6S8(CN) 4(H2O)Br] (3), (Me4N)3(H 5O2)[Re6S8(CN)4Br 2] (4), and CsK{Cu(H2O)2[Re6S 8(CN)4Cl2]} • 4H2O (5) salts.
