The crystal structure described by YbNi crystallizes in the orthorhombic Pnma space group. Yb(1) is bonded in a 7-coordinate geometry to seven equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to seven equivalent Yb(1) and two equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
