TiTcAg2 crystallizes in the monoclinic Cm space group. Ti(1) is bonded in a 1-coordinate geometry to one Ag(1) and three equivalent Ag(2) atoms. The Ti(1)-Ag(1) bond length is 2.33 Å. There is one shorter (3.27 Å) and two longer (3.58 Å) Ti(1)-Ag(2) bond lengths. Tc(1) is bonded in a 2-coordinate geometry to one Ag(1) and four equivalent Ag(2) atoms. The Tc(1)-Ag(1) bond length is 2.45 Å. There are a spread of Tc(1)-Ag(2) bond distances ranging from 2.45-3.18 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 1-coordinate geometry to one Ti(1) and one Tc(1) atom. In the second Ag site, Ag(2) is bonded in a 11-coordinate geometry to three equivalent Ti(1), four equivalent Tc(1), and four equivalent Ag(2) atoms. All Ag(2)-Ag(2) bond lengths are 2.72 Å.
