Mn V V C
V2MnC crystallizes in the trigonal R3m space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 10-coordinate geometry to three equivalent V(2), three equivalent Mn(1), and four equivalent C(1) atoms. All V(1)-V(2) bond lengths are 2.24 Å. All V(1)-Mn(1) bond lengths are 2.24 Å. There are three shorter (2.29 Å) and one longer (2.60 Å) V(1)-C(1) bond length. In the second V site, V(2) is bonded in a 10-coordinate geometry to three equivalent V(1), four equivalent Mn(1), and three equivalent C(1) atoms. There are three shorter (2.29 Å) and one longer (2.60 Å) V(2)-Mn(1) bond length. All V(2)-C(1) bond lengths are 2.24 Å. Mn(1) is bonded in a single-bond geometry to three equivalent V(1), four equivalent V(2), and one C(1) atom. The Mn(1)-C(1) bond length is 0.81 Å. C(1) is bonded in a single-bond geometry to three equivalent V(2), four equivalent V(1), and one Mn(1) atom.
