CaTcGaPb crystallizes in the trigonal R3m space group. Ca(1) is bonded in a 10-coordinate geometry to three equivalent Tc(1), four equivalent Ga(1), and three equivalent Pb(1) atoms. All Ca(1)-Tc(1) bond lengths are 2.90 Å. There is one shorter (2.77 Å) and three longer (3.19 Å) Ca(1)-Ga(1) bond lengths. All Ca(1)-Pb(1) bond lengths are 3.24 Å. Tc(1) is bonded in a 4-coordinate geometry to three equivalent Ca(1), three equivalent Ga(1), and four equivalent Pb(1) atoms. All Tc(1)-Ga(1) bond lengths are 3.24 Å. There is one shorter (2.77 Å) and three longer (3.19 Å) Tc(1)-Pb(1) bond lengths. Ga(1) is bonded in a 11-coordinate geometry to four equivalent Ca(1), three equivalent Tc(1), and four equivalent Pb(1) atoms. There is one shorter (2.77 Å) and three longer (3.19 Å) Ga(1)-Pb(1) bond lengths. Pb(1) is bonded in a 11-coordinate geometry to three equivalent Ca(1), four equivalent Tc(1), and four equivalent Ga(1) atoms.
