Materials Data on LaSbPt by Materials Project

LaPtSb crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. La3+ is bonded in a 2-coordinate geometry to six equivalent Pt2- and four equivalent Sb1- atoms. There are a spread of La–Pt bond distances ranging from 2.93–3.48 Å. There are a spread of La–Sb bond distances ranging from 3.42–3.52 Å. Pt2- is bonded in a 9-coordinate geometry to six equivalent La3+ and three equivalent Pt2- atoms. There are two shorter (2.74 Å) and one longer (2.89 Å) Pt–Pt bond lengths. Sb1- is bonded to four equivalent La3+ and three equivalent Sb1- atoms to form distorted edge-sharing SbLa4Sb3 pentagonal bipyramids. There are two shorter (2.84 Å) and one longer (3.07 Å) Sb–Sb bond lengths.
