Crystal structure of tris (phenylammonium) chloride pentachloroantimonate (III) monohydrate

The tris (phenylammonium) chloride pentachloroantimonate (III) monohydrate salt is triclinic P (1) over bar with the following cell parameters: a=9.4283(3), b=11.4482(3), c=13.1748(3) Angstrom, alpha=113.493(2), beta=90.381(2), gamma=97.331(1)degrees, V=1290.86(6) Angstrom(3), with Z=2 formula units. The structure consists of [C6H5NH3](+) cations, water molecules, Cl- anions, and SbCl5 square pyramids. Hydrogen bonds, established through water molecule, link the anions [SbCl5](2-) and Cl- and make an infinite chain in the [011] direction. Chains are linked together via another hydrogen bond network originating from the ammonium groups. A distortion of the SbCl5 square pyramid can be attributed to the stereo activity of the Sb(III) lone electron pair.
