The crystal structure described by NiSiN2 crystallizes in the hexagonal P6_3/mmc space group. Ni(1) is bonded in a linear geometry to two equivalent N(1) atoms. Si(1) is bonded in a 6-coordinate geometry to six equivalent N(1) atoms. N(1) is bonded in a rectangular see-saw-like geometry to one Ni(1) and three equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
