Abstract

Two new anions [Nb₆Fⁱ₆Xⁱ₆(NCS)^a₆]⁴⁻ (X = Br, I) based on octahedral niobium clusters with edge-bridging F ligands have been prepared by reaction of Cs₃Nb₆F₆Br₁₂ and Cs₄Nb₆F_8.5I_9.5 with aqueous solution of KSCN. The anions were isolated as (Et₄N)₆[Nb₆F₆Br₆(NCS)₆]Br₂ (1) and Cs_1.6K_2.4[Nb₆F₆I₆(NCS)₆] (2) salts.
