Bis(tetra-butyl-ammonium) [2-(eth-oxy-carbony)phenyl-imido]-μ(6)-oxido-dodeca-μ(2)-oxido-penta-oxidohexa-molybdenum diethyl ether hemisolvate.
In the title complex, [(C(4)H(9))(4)N](2)[Mo(6)O(18)(C(9)H(9)NO(2))]·0.5C(4)H(10)O, the aryl-imido ligand is linked to an Mo atom of the Lindqvist-type polyoxidometalate anion by an Mo N bond of 1.726 (4) Å. The Mo N-C angles are 160.7 (5) and 167.6(5)° because of disorder affecting the aryl group, and is typical for the imido monodentate behaviour described in analogous hybrids. Light components of the structure are extensively disordered. The aryl ester group is disordered over two positions with occupancies refined to 0.559 (3) and 0.441 (3). Both independent tetra-butyl-ammonium cations have butyl chains partially split over two sites, with occupancies as in the aryl group of the anion. Finally, the ether solvent mol-ecule is disordered around an inversion centre. In the crystal, cations and anions inter-act via C-H⋯O contacts, involving O atoms of the polyoxidometalate anion and the ester group of the aryl-imido ligand as acceptor groups.
