Materials Data on PrSbSe by Materials Project
PrSbSe is Matlockite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Pr3+ is bonded in a 5-coordinate geometry to four equivalent Sb1- and five equivalent Se2- atoms. There are a spread of Pr–Sb bond distances ranging from 3.43–3.50 Å. There are a spread of Pr–Se bond distances ranging from 3.07–3.11 Å. Sb1- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Sb1- atoms. There are a spread of Sb–Sb bond distances ranging from 2.87–3.16 Å. Se2- is bonded to five equivalent Pr3+ atoms to form a mixture of distorted edge and corner-sharing SePr5 trigonal bipyramids.
