Materials Data on K2MnH4(Cl2O)2 by Materials Project
K2MnH4(OCl2)2 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. K1+ is bonded in a body-centered cubic geometry to eight equivalent Cl1- atoms. There are four shorter (3.32 Å) and four longer (3.39 Å) K–Cl bond lengths. Mn2+ is bonded in an octahedral geometry to two equivalent O2- and four equivalent Cl1- atoms. Both Mn–O bond lengths are 2.21 Å. All Mn–Cl bond lengths are 2.55 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. O2- is bonded in a distorted trigonal planar geometry to one Mn2+ and two equivalent H1+ atoms. Cl1- is bonded in a distorted single-bond geometry to four equivalent K1+ and one Mn2+ atom.
