Materials Data on Mn(ReO5)2 by Materials Project
Mn(ReO5)2 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two Mn(ReO5)2 ribbons oriented in the (0, 1, 0) direction. Re+6.50+ is bonded to four O2- atoms to form ReO4 tetrahedra that share corners with two equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 25°. There is two shorter (1.73 Å) and two longer (1.78 Å) Re–O bond length. Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent ReO4 tetrahedra. There are two shorter (1.95 Å) and four longer (2.06 Å) Mn–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Re+6.50+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Re+6.50+ and one Mn7+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Mn7+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Re+6.50+ atom.
