Mg Mg Tc Pd
MgTcMgPd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two magnesium-palladium molecules and two MgTc clusters. In each MgTc cluster, Mg(2) is bonded in a distorted single-bond geometry to one Tc(1) atom. The Mg(2)-Tc(1) bond length is 1.47 Å. Tc(1) is bonded in a distorted single-bond geometry to one Mg(2) atom.
