Abstract
The title compound, [Nb(6)Cl(12)I(2)(H(2)O)(4)]·8THF (THF is tetra-hydro-furan, C(4)H(8)O), comprises an uncharged niobium cluster unit surrounded by THF solvent mol-ecules. The edges of the {Nb(6)} octa-hedron are μ (2)-coordinated by twelve chlorido ligands. Four in-plane (equatorial plane) aqua ligands and two iodido ligands coordinating above and below the plane are bound at the corners of the {Nb(6)} atomic octa-hedron. O-H⋯O hydrogen bonds are formed between the aqua ligands and the THF solvent mol-ecules; one THF molecule is disordered over two positions with the major component having a site occupancy of 0.64 (2).
