Rh6C7 crystallizes in the triclinic P1 space group. There are six inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a linear geometry to one Rh(3) and one C(7) atom. The Rh(1)-Rh(3) bond length is 0.42 Å. The Rh(1)-C(7) bond length is 0.25 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Rh(4), one Rh(6), and one C(3) atom. The Rh(2)-Rh(4) bond length is 0.42 Å. The Rh(2)-Rh(6) bond length is 1.91 Å. The Rh(2)-C(3) bond length is 2.26 Å. In the third Rh site, Rh(3) is bonded in a distorted single-bond geometry to one Rh(1), one C(1), one C(6), and two equivalent C(5) atoms. The Rh(3)-C(1) bond length is 2.09 Å. The Rh(3)-C(6) bond length is 2.08 Å. There is one shorter (2.20 Å) and one longer (2.48 Å) Rh(3)-C(5) bond length. In the fourth Rh site, Rh(4) is bonded in a distorted single-bond geometry to one Rh(2), one C(2), one C(4), and two equivalent C(3) atoms. The Rh(4)-C(2) bond length is 2.08 Å. The Rh(4)-C(4) bond length is 2.09 Å. There is one shorter (2.20 Å) and one longer (2.48 Å) Rh(4)-C(3) bond length. In the fifth Rh site, Rh(5) is bonded in a linear geometry to one Rh(6) and one C(7) atom. The Rh(5)-Rh(6) bond length is 0.46 Å. The Rh(5)-C(7) bond length is 1.66 Å. In the sixth Rh site, Rh(6) is bonded in a linear geometry to one Rh(2) and one Rh(5) atom. There are seven inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 150 degrees geometry to one Rh(3), one C(3), and one C(5) atom. The C(1)-C(3) bond length is 1.66 Å. The C(1)-C(5) bond length is 2.07 Å. In the second C site, C(2) is bonded in a distorted water-like geometry to one Rh(4) and one C(3) atom. The C(2)-C(3) bond length is 1.86 Å. In the third C site, C(3) is bonded in a 6-coordinate geometry to one Rh(2), two equivalent Rh(4), one C(1), one C(2), and one C(4) atom. The C(3)-C(4) bond length is 2.07 Å. In the fourth C site, C(4) is bonded in a distorted bent 150 degrees geometry to one Rh(4), one C(3), and one C(5) atom. The C(4)-C(5) bond length is 1.66 Å.
