Refinement of the Molecular Structure of Ammonium Pentachloroaquaferrate (NH4)2[FeCl5(H2O)]

Abstract: The crystal structure of ammonium pentachloroaquaferrate (NH4)2[FeCl5(H2O)] is refined (CIF file CCDC no. 1831198). Compounds (А)х[FeCl5(H2O)], where A is an organic or inorganic anion (х = 1, 2), crystallize in the orthorhombic crystal system. The geometry and structural parameters of the [FeCl5(H2O)]2– anion are nearly independent of the counterion nature. © 2019, Pleiades Publishing, Ltd.
