Tm Pa
PaTm crystallizes in the monoclinic Cm space group. Pa(1) is bonded in a 12-coordinate geometry to four equivalent Pa(1) and eight equivalent Tm(1) atoms. All Pa(1)-Pa(1) bond lengths are 3.24 Å. There are a spread of Pa(1)-Tm(1) bond distances ranging from 2.89-3.98 Å. Tm(1) is bonded in a 12-coordinate geometry to eight equivalent Pa(1) and four equivalent Tm(1) atoms. All Tm(1)-Tm(1) bond lengths are 3.24 Å.
