Gd6CoCl10 crystallizes in the triclinic P-1 space group. There are three inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to one Co(1), one Cl(1), one Cl(2), one Cl(3), and two equivalent Cl(4) atoms to form a mixture of edge and corner-sharing GdCoCl5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the second Gd site, Gd(2) is bonded to one Co(1), one Cl(2), one Cl(3), one Cl(5), and two equivalent Cl(1) atoms to form a mixture of edge and corner-sharing GdCoCl5 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the third Gd site, Gd(3) is bonded to one Co(1), one Cl(3), one Cl(4), one Cl(5), and two equivalent Cl(2) atoms to form a mixture of edge and corner-sharing GdCoCl5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. Co(1) is bonded in an octahedral geometry to two equivalent Gd(1), two equivalent Gd(2), and two equivalent Gd(3) atoms. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a T-shaped geometry to one Gd(1) and two equivalent Gd(2) atoms. In the second Cl site, Cl(2) is bonded in a see-saw-like geometry to one Gd(1), one Gd(2), and two equivalent Gd(3) atoms. In the third Cl site, Cl(3) is bonded in a distorted trigonal non-coplanar geometry to one Gd(1), one Gd(2), and one Gd(3) atom. In the fourth Cl site, Cl(4) is bonded in a T-shaped geometry to one Gd(3) and two equivalent Gd(1) atoms. In the fifth Cl site, Cl(5) is bonded in an L-shaped geometry to one Gd(2) and one Gd(3) atom.
