Materials Data on Pr2CoSi3 by Materials Project
Pr2CoSi3 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Pr4+ is bonded in a distorted q4 geometry to nine Si4- atoms. There are three shorter (3.15 Å) and six longer (3.21 Å) Pr–Si bond lengths. Co4+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Co–Si bond lengths are 2.33 Å. There are three inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 9-coordinate geometry to six equivalent Pr4+ and three equivalent Si4- atoms. All Si–Si bond lengths are 2.33 Å. In the second Si4- site, Si4- is bonded in a 9-coordinate geometry to six equivalent Pr4+ and three equivalent Co4+ atoms. In the third Si4- site, Si4- is bonded in a 9-coordinate geometry to six equivalent Pr4+ and three equivalent Si4- atoms.
