Re2CoAg crystallizes in the triclinic P1 space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 3-coordinate geometry to one Re(2), one Co(1), and one Ag(1) atom. The Re(1)-Re(2) bond length is 2.04 Å. The Re(1)-Co(1) bond length is 2.02 Å. The Re(1)-Ag(1) bond length is 2.16 Å. In the second Re site, Re(2) is bonded in a 2-coordinate geometry to one Re(1) and two equivalent Co(1) atoms. There is one shorter (2.19 Å) and one longer (2.81 Å) Re(2)-Co(1) bond length. Co(1) is bonded in a 7-coordinate geometry to one Re(1), two equivalent Re(2), two equivalent Co(1), and two equivalent Ag(1) atoms. Both Co(1)-Co(1) bond lengths are 2.67 Å. There is one shorter (2.41 Å) and one longer (2.72 Å) Co(1)-Ag(1) bond length. Ag(1) is bonded in a 2-coordinate geometry to one Re(1) and two equivalent Co(1) atoms.
