V6C5 crystallizes in the trigonal P3_112 space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one C(1), one C(2), one C(3), one C(4), and one C(5) atom to form a mixture of corner and edge-sharing VC5 square pyramids. In the second V site, V(2) is bonded to one C(1), one C(2), one C(3), one C(4), and one C(5) atom to form a mixture of corner and edge-sharing VC5 square pyramids. In the third V site, V(3) is bonded to one C(1), one C(2), one C(3), one C(4), and one C(5) atom to form a mixture of corner and edge-sharing VC5 square pyramids. There are five inequivalent C sites. In the first C site, C(1) is bonded to two equivalent V(1), two equivalent V(2), and two equivalent V(3) atoms to form a mixture of corner and edge-sharing CV6 octahedra. The corner-sharing octahedral tilt angles range from 8-9°. In the second C site, C(2) is bonded to two equivalent V(1), two equivalent V(2), and two equivalent V(3) atoms to form a mixture of corner and edge-sharing CV6 octahedra. The corner-sharing octahedral tilt angles are 7°.
