Re Tc Ag Ag
ReTcAg2 crystallizes in the monoclinic Cm space group. Re(1) is bonded in a 10-coordinate geometry to two equivalent Re(1) and eight equivalent Ag(1) atoms. Both Re(1)-Re(1) bond lengths are 2.68 Å. There are a spread of Re(1)-Ag(1) bond distances ranging from 2.44-3.19 Å. Tc(1) is bonded in a 10-coordinate geometry to two equivalent Tc(1) and eight equivalent Ag(1) atoms. Both Tc(1)-Tc(1) bond lengths are 2.68 Å. There are a spread of Tc(1)-Ag(1) bond distances ranging from 2.44-3.19 Å. Ag(1) is bonded in a 10-coordinate geometry to four equivalent Re(1), four equivalent Tc(1), and two equivalent Ag(1) atoms. Both Ag(1)-Ag(1) bond lengths are 2.68 Å.
