Materials Data on PmCl2 by Materials Project
PmCl2 is zeta iron carbide structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Pm is bonded to six equivalent Cl atoms to form a mixture of edge and corner-sharing PmCl6 octahedra. The corner-sharing octahedral tilt angles are 39°. There are two shorter (2.82 Å) and four longer (2.84 Å) Pm–Cl bond lengths. Cl is bonded in a 3-coordinate geometry to three equivalent Pm atoms.
