Pm Tc
PmTc is Tetraauricupride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PmTc clusters. Pm(1) is bonded in a distorted single-bond geometry to one Tc(1) atom. The Pm(1)-Tc(1) bond length is 1.54 Å. Tc(1) is bonded in a distorted single-bond geometry to one Pm(1) atom.
