Abstract:
The title compound, As[C6H3(CF3)(2)](3), has been synthesised by
Grignard reaction from arsenic trichloride and
3,5-bis(trifluoromethyl)phenylmagnesium bromide. It crystallises in the
triclinic space group P (1) over bar with two formula units in the
asymmetric unit. The most prominent feature of the crystal structure is
the protrusion of a phenyl group of one molecule into the cavity at the
base of the pyramid of a second molecule. The crystal structure is then
built up by densely packing these units of interlocked molecules to
form columns, which are arranged in parallel in a distorted hexagonal
pattern.
