New structural units in molybdenum oxyfluoride chemistry

This article was supported with EPSRC funding.The solvothermal syntheses and crystal structures of five new molybdenum oxyfluorides are presented. These exhibit three novel structural units, each containing Mo in a reduced oxidation state: a dimeric [MO2O4F2(C2H8N2)(2)] unit (Mo4+), a tetrameric [Mo4O8F10](6-) unit (Mo5+) and an infinite chain [MoOF3](-) unit (Mo4+). Mo-Mo bonding is observed in each of the new building units.PostprintPeer reviewe
