Materials Data on Mn(HCl)2 by Materials Project
Mn(HCl)2 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two Mn(HCl)2 ribbons oriented in the (0, 0, 1) direction. Mn2+ is bonded to two equivalent H and four equivalent Cl1- atoms to form edge-sharing MnH2Cl4 octahedra. Both Mn–H bond lengths are 1.66 Å. There are two shorter (2.31 Å) and two longer (2.32 Å) Mn–Cl bond lengths. H is bonded in a single-bond geometry to one Mn2+ atom. Cl1- is bonded in an L-shaped geometry to two equivalent Mn2+ atoms.
