The structure described by CrNbSi crystallizes in the hexagonal P-62m space group. Nb(1) is bonded in a 11-coordinate geometry to six equivalent Cr(1), one Si(1), and four equivalent Si(2) atoms. Cr(1) is bonded in a 4-coordinate geometry to six equivalent Nb(1), two equivalent Si(1), and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to three equivalent Nb(1) and six equivalent Cr(1) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to six equivalent Nb(1) and three equivalent Cr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
