Tetra-aqua-dodekakis-μ-chlorido-di-iodido--hexa-niobium(12 -) tetra-hydro-furan octa-solvate.

The title compound, [NbClI(HO)]·8THF (THF is tetra-hydro-furan, CHO), comprises an uncharged niobium cluster unit surrounded by THF solvent mol-ecules. The edges of the {Nb} octa-hedron are -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} 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).
