Materials Data on EuP3 by Materials Project

EuP3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Eu2+ is bonded in a 7-coordinate geometry to nine P+0.67- atoms. There are a spread of Eu–P bond distances ranging from 2.95–3.32 Å. There are two inequivalent P+0.67- sites. In the first P+0.67- site, P+0.67- is bonded in a distorted tetrahedral geometry to one Eu2+ and three P+0.67- atoms. There are two shorter (2.23 Å) and one longer (2.29 Å) P–P bond lengths. In the second P+0.67- site, P+0.67- is bonded in a 6-coordinate geometry to four equivalent Eu2+ and two P+0.67- atoms. The P–P bond length is 2.25 Å.

Materials Data on EuP3 by Materials Project

EuP3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Eu2+ sites. In the first Eu2+ site, Eu2+ is bonded in a 7-coordinate geometry to ten P+0.67- atoms. There are a spread of Eu–P bond distances ranging from 2.98–3.49 Å. In the second Eu2+ site, Eu2+ is bonded in a 9-coordinate geometry to nine P+0.67- atoms. There are a spread of Eu–P bond distances ranging from 2.96–3.39 Å. There are four inequivalent P+0.67- sites. In the first P+0.67- site, P+0.67- is bonded in a 4-coordinate geometry to two Eu2+ and three P+0.67- atoms. There are two shorter (2.19 Å) and one longer (2.26 Å) P–P bond lengths. In the second P+0.67- site, P+0.67- is bonded in a distorted tetrahedral geometry to one Eu2+ and three P+0.67- atoms. Both P–P bond lengths are 2.22 Å. In the third P+0.67- site, P+0.67- is bonded in a 6-coordinate geometry to four Eu2+ and two P+0.67- atoms. The P–P bond length is 2.20 Å. In the fourth P+0.67- site, P+0.67- is bonded in a 5-coordinate geometry to four Eu2+ and two P+0.67- atoms. The P–P bond length is 2.24 Å.
