Arsenic pentafluoride

It is a toxic, colorless gas.

Arsenic pentafluoride is a colourless gas and has a trigonal bipyramidal structure.

[3] In the solid state the axial As−F bond lengths are 171.9 pm and the equatorial 166.8 pm.

Arsenic pentafluoride forms halide complexes and is a powerful fluoride acceptor.

An example is the reaction with sulfur tetrafluoride, forming an ionic hexafluoroarsenate complex.
