Materials Data on KNd2Br5 by Materials Project
KNd2Br5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of K–Br bond distances ranging from 3.16–3.73 Å. There are two inequivalent Nd2+ sites. In the first Nd2+ site, Nd2+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of Nd–Br bond distances ranging from 2.95–3.82 Å. In the second Nd2+ site, Nd2+ is bonded in a 7-coordinate geometry to seven Br1- atoms. There are a spread of Nd–Br bond distances ranging from 3.01–3.35 Å. There are five inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 4-coordinate geometry to two equivalent K1+ and two equivalent Nd2+ atoms. In the second Br1- site, Br1- is bonded in a 4-coordinate geometry to two equivalent K1+ and three Nd2+ atoms. In the third Br1- site, Br1- is bonded in a 5-coordinate geometry to two equivalent K1+ and three Nd2+ atoms. In the fourth Br1- site, Br1- is bonded in a 5-coordinate geometry to two equivalent K1+ and three Nd2+ atoms. In the fifth Br1- site, Br1- is bonded in a 4-coordinate geometry to four Nd2+ atoms.
