PmI is Tungsten Carbide structured and crystallizes in the hexagonal P-6m2 space group. Pm(1) is bonded in a 6-coordinate geometry to six equivalent I(1) atoms. I(1) is bonded to six equivalent Pm(1) atoms to form a mixture of distorted corner, edge, and face-sharing IPm6 pentagonal pyramids.
PmI is Tungsten Carbide structured and crystallizes in the hexagonal P-6m2 space group. Pm(1) is bonded in a 6-coordinate geometry to six equivalent I(1) atoms. All Pm(1)-I(1) bond lengths are 3.25 Å. I(1) is bonded to six equivalent Pm(1) atoms to form a mixture of distorted corner, edge, and face-sharing IPm6 pentagonal pyramids.
