Materials Data on ErNiBC by Materials Project
ErNiBC crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Er3+ is bonded to five equivalent C2- atoms to form a mixture of edge and corner-sharing ErC5 square pyramids. There are one shorter (2.40 Å) and four longer (2.51 Å) Er–C bond lengths. Ni2+ is bonded to four equivalent B3- atoms to form NiB4 tetrahedra that share corners with four equivalent CEr5B octahedra, corners with four equivalent NiB4 tetrahedra, and edges with four equivalent NiB4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. All Ni–B bond lengths are 2.10 Å. B3- is bonded in a distorted single-bond geometry to four equivalent Ni2+ and one C2- atom. The B–C bond length is 1.50 Å. C2- is bonded to five equivalent Er3+ and one B3- atom to form distorted CEr5B octahedra that share corners with four equivalent CEr5B octahedra, corners with four equivalent NiB4 tetrahedra, and edges with eight equivalent CEr5B octahedra. The corner-sharing octahedral tilt angles are 4°.
