Re2CoGa crystallizes in the monoclinic Cm space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to one Re(2), six equivalent Re(1), and one Co(1) atom to form distorted ReCoRe7 hexagonal bipyramids that share corners with six equivalent Re(1)CoRe7 hexagonal bipyramids, edges with six equivalent Re(2)GaRe7 hexagonal bipyramids, and edges with twelve equivalent Re(1)CoRe7 hexagonal bipyramids. The Re(1)-Re(2) bond length is 2.32 Å. All Re(1)-Re(1) bond lengths are 2.73 Å. The Re(1)-Co(1) bond length is 2.89 Å. In the second Re site, Re(2) is bonded to one Re(1), six equivalent Re(2), and one Ga(1) atom to form distorted ReGaRe7 hexagonal bipyramids that share corners with six equivalent Re(2)GaRe7 hexagonal bipyramids, edges with six equivalent Re(1)CoRe7 hexagonal bipyramids, and edges with twelve equivalent Re(2)GaRe7 hexagonal bipyramids. All Re(2)-Re(2) bond lengths are 2.73 Å. The Re(2)-Ga(1) bond length is 3.23 Å. Co(1) is bonded in a single-bond geometry to one Re(1) and one Ga(1) atom. The Co(1)-Ga(1) bond length is 0.34 Å. Ga(1) is bonded in a single-bond geometry to one Re(2) and one Co(1) atom.
