Materials Data on Nd2Tc2O7 by Materials Project

Nd2Tc2O7 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Nd3+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are two shorter (2.28 Å) and six longer (2.57 Å) Nd–O bond lengths. Tc4+ is bonded to six equivalent O2- atoms to form corner-sharing TcO6 octahedra. The corner-sharing octahedral tilt angles are 50°. All Tc–O bond lengths are 2.06 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Nd3+ and two equivalent Tc4+ atoms to form a mixture of distorted corner and edge-sharing ONd2Tc2 tetrahedra. In the second O2- site, O2- is bonded to four equivalent Nd3+ atoms to form a mixture of corner and edge-sharing ONd4 tetrahedra.
