Materials Data on La(Ni2B)6 by Materials Project
La(Ni2B)6 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. La3+ is bonded in a distorted hexagonal planar geometry to six B3- atoms. There are a spread of La–B bond distances ranging from 3.08–3.30 Å. There are seven inequivalent Ni+1.25+ sites. In the first Ni+1.25+ site, Ni+1.25+ is bonded in a distorted T-shaped geometry to three B3- atoms. There are a spread of Ni–B bond distances ranging from 2.02–2.10 Å. In the second Ni+1.25+ site, Ni+1.25+ is bonded to four B3- atoms to form a mixture of distorted corner and edge-sharing NiB4 tetrahedra. There are a spread of Ni–B bond distances ranging from 2.02–2.12 Å. In the third Ni+1.25+ site, Ni+1.25+ is bonded to four B3- atoms to form a mixture of distorted corner and edge-sharing NiB4 tetrahedra. There are a spread of Ni–B bond distances ranging from 2.03–2.13 Å. In the fourth Ni+1.25+ site, Ni+1.25+ is bonded in a distorted T-shaped geometry to three B3- atoms. There are a spread of Ni–B bond distances ranging from 2.05–2.15 Å. In the fifth Ni+1.25+ site, Ni+1.25+ is bonded to four B3- atoms to form a mixture of corner and edge-sharing NiB4 tetrahedra. There are a spread of Ni–B bond distances ranging from 2.00–2.10 Å. In the sixth Ni+1.25+ site, Ni+1.25+ is bonded in a T-shaped geometry to three B3- atoms. There are two shorter (2.00 Å) and one longer (2.06 Å) Ni–B bond lengths. In the seventh Ni+1.25+ site, Ni+1.25+ is bonded in a T-shaped geometry to three B3- atoms. There are two shorter (2.09 Å) and one longer (2.17 Å) Ni–B bond lengths. There are four inequivalent B3- sites. In the first B3- site, B3- is bonded in a 7-coordinate geometry to one La3+ and seven Ni+1.25+ atoms. In the second B3- site, B3- is bonded in a 7-coordinate geometry to one La3+ and seven Ni+1.25+ atoms. In the third B3- site, B3- is bonded in a 7-coordinate geometry to one La3+ and seven Ni+1.25+ atoms. In the fourth B3- site, B3- is bonded in a 7-coordinate geometry to one La3+ and seven Ni+1.25+ atoms.
