The material structure described by V10BSi6 crystallizes in the trigonal P-31m space group. There are three inequivalent V sites. In the first V site, V(1) is bonded in a 6-coordinate geometry to one B(1) and five equivalent Si(1) atoms. In the second V site, V(2) is bonded in a 8-coordinate geometry to two equivalent V(3) and six equivalent Si(1) atoms. In the third V site, V(3) is bonded in a 8-coordinate geometry to two equivalent V(2) and six equivalent Si(1) atoms. B(1) is bonded in an octahedral geometry to six equivalent V(1) atoms. Si(1) is bonded in a 9-coordinate geometry to two equivalent V(2), two equivalent V(3), and five equivalent V(1) atoms. is represented by the CIF file [CIF]
