title: A new hybrid framework based on a 'superoctahedral' [V7O6F30](14-) polyanion.
abstract: Solvothermal synthesis has led to the isolation of an unusual hybrid framework solid [CH3NH3]8[Cu(Py)4]3[V7O6F30] in which the novel [V7O6F30](14-) polyanion is linked via [Cu(py)4]2+ moieties into a doubly interpenetrated cubic lattice.
