MgHfMoTc crystallizes in the trigonal R3m space group. Mg(1) is bonded in a single-bond geometry to three equivalent Hf(1), four equivalent Mo(1), and one Tc(1) atom. All Mg(1)-Hf(1) bond lengths are 2.69 Å. There are three shorter (2.81 Å) and one longer (2.83 Å) Mg(1)-Mo(1) bond length. The Mg(1)-Tc(1) bond length is 1.39 Å. Hf(1) is bonded in a 10-coordinate geometry to three equivalent Mg(1), three equivalent Mo(1), and four equivalent Tc(1) atoms. All Hf(1)-Mo(1) bond lengths are 2.69 Å. There are three shorter (2.81 Å) and one longer (2.83 Å) Hf(1)-Tc(1) bond length. Mo(1) is bonded in a 10-coordinate geometry to four equivalent Mg(1), three equivalent Hf(1), and three equivalent Tc(1) atoms. All Mo(1)-Tc(1) bond lengths are 2.69 Å. Tc(1) is bonded in a single-bond geometry to one Mg(1), four equivalent Hf(1), and three equivalent Mo(1) atoms.
