Mg V Cr
MgVCr crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 11-coordinate geometry to six equivalent Mg(1), two equivalent V(1), and three equivalent Cr(1) atoms. All Mg(1)-Mg(1) bond lengths are 2.68 Å. There is one shorter (3.57 Å) and one longer (3.66 Å) Mg(1)-V(1) bond length. There are a spread of Mg(1)-Cr(1) bond distances ranging from 2.64-2.91 Å. V(1) is bonded in a distorted single-bond geometry to two equivalent Mg(1) and one Cr(1) atom. The V(1)-Cr(1) bond length is 1.60 Å. Cr(1) is bonded in a distorted single-bond geometry to three equivalent Mg(1) and one V(1) atom.
