The structure described by Ba(NiSi)2 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent Ni(1) and four equivalent Si(1) atoms. Ni(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 7-coordinate geometry to two equivalent Ba(1), four equivalent Ni(1), and one Si(1) atom. is represented by the CIF file [CIF]
