NpIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Np(1) is bonded to twelve equivalent In(1) atoms to form NpIn12 cuboctahedra that share corners with twelve equivalent Np(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)Np4In8 cuboctahedra, faces with six equivalent Np(1)In12 cuboctahedra, and faces with twelve equivalent In(1)Np4In8 cuboctahedra. In(1) is bonded to four equivalent Np(1) and eight equivalent In(1) atoms to form distorted InNp4In8 cuboctahedra that share corners with twelve equivalent In(1)Np4In8 cuboctahedra, edges with eight equivalent Np(1)In12 cuboctahedra, edges with sixteen equivalent In(1)Np4In8 cuboctahedra, faces with four equivalent Np(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)Np4In8 cuboctahedra.
