The structure described by Nb2(VSi)3 crystallizes in the hexagonal P6_3/mcm space group. Nb(1) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. V(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to four equivalent Nb(1) and five equivalent V(1) atoms. is represented by the CIF file [CIF]
