Title: Materials Data on Sm4(CoB2)3 by Materials Project

Abstract

(Sm2CoB3)2Co crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three cobalt molecules and three Sm2CoB3 sheets oriented in the (0, 0, 1) direction. In each Sm2CoB3 sheet, there are two inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 6-coordinate geometry to six equivalent B3- atoms. All Sm–B bond lengths are 2.70 Å. In the second Sm3+ site, Sm3+ is bonded in a 6-coordinate geometry to six equivalent B3- atoms. All Sm–B bond lengths are 2.68 Å. Co2+ is bonded in a 6-coordinate geometry to six equivalent B3- atoms. All Co–B bond lengths are 2.14 Å. B3- is bonded in a 9-coordinate geometry to four Sm3+, two equivalent Co2+, and three equivalent B3- atoms. There is two shorter (1.78 Å) and one longer (1.79 Å) B–B bond length.
