Materials Data on NiSb2 by Materials Project
NiSb2 is Marcasite structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Ni2+ is bonded to six equivalent Sb1- atoms to form a mixture of edge and corner-sharing NiSb6 octahedra. The corner-sharing octahedral tilt angles are 55°. There are two shorter (2.55 Å) and four longer (2.59 Å) Ni–Sb bond lengths. Sb1- is bonded in a 4-coordinate geometry to three equivalent Ni2+ and one Sb1- atom. The Sb–Sb bond length is 2.91 Å.
