The material described by VNiSi crystallizes in the orthorhombic Pnma space group. V(1) is bonded in a 11-coordinate geometry to six equivalent Ni(1) and five equivalent Si(1) atoms. Ni(1) is bonded to six equivalent V(1), two equivalent Ni(1), and four equivalent Si(1) atoms to form a mixture of distorted corner, face, and edge-sharing NiV6Si4Ni2 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to five equivalent V(1) and four equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
