Gd(NiAs)2 crystallizes in the tetragonal I4/mmm space group. Gd(1) is bonded in a 16-coordinate geometry to eight equivalent Ni(1) and eight equivalent As(1) atoms. Ni(1) is bonded to four equivalent Gd(1) and four equivalent As(1) atoms to form a mixture of distorted edge, face, and corner-sharing NiGd4As4 tetrahedra. As(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), four equivalent Ni(1), and one As(1) atom.
