The crystal structure described by Sr(Pt3B2)2 crystallizes in the trigonal P-3m1 space group. Sr(1) is bonded to twelve equivalent Pt(1) atoms to form edge-sharing SrPt12 cuboctahedra. Pt(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), two equivalent B(1), and two equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 7-coordinate geometry to six equivalent Pt(1) and one B(2) atom. In the second B site, B(2) is bonded in a 7-coordinate geometry to six equivalent Pt(1) and one B(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
