The preparations and spectroscopic characterisation of the hydrolytically unstable As(III) complexes, [AsF3(OPR3)2] (R = Me or Ph) and [AsF3Me2P(O)CH2P(O)Me2}] are described and represent the first examples of complexes of AsF3 with neutral ligands. The crystal structure of [AsF3Me2P(O)CH2P(O)Me2}] contains dimers with bridging diphosphine dioxide, but there are also long contacts between the dimers
