The material described by SmNiC2 crystallizes in the orthorhombic Amm2 space group. Sm(1) is bonded in a 8-coordinate geometry to eight equivalent C(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to four equivalent C(1) atoms. C(1) is bonded in a 7-coordinate geometry to four equivalent Sm(1), two equivalent Ni(1), and one C(1) atom. is represented by the CIF card [CIF]
