Abstract

The crystal structure of the title compound, (NH4)2 [FeCl5(H2O)], has been redetermined by single-crystal X-ray diffraction at 295 K and refined by full matrix least squares to a residual of 0.054 for 1662 'observed' reflections. Crystals are orthorhombic, Pnma, a 13.706(2), b 9.924(1), c 7.024(1)Ǻ Z 4. Fe-O is 2.110(4)Ǻ; Fe-Cl range between 2.323(1)Ǻ (trans to OH2) and 2.350(1)-2.390(1) Ǻ (cis), the latter distances being very dependent upon hydrogen-bonded interactions with nearby species.
