Materials Data on MnH8(BrO2)2 by Materials Project
MnH8(O2Br)2 is alpha U structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four manganese(ii) bromide tetrahydrate molecules. Mn2+ is bonded in an octahedral geometry to four O2- and two Br1- atoms. There are a spread of Mn–O bond distances ranging from 2.19–2.29 Å. There are one shorter (2.66 Å) and one longer (2.70 Å) Mn–Br bond lengths. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Mn2+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Mn2+ atom.
