The crystal structure described by La2CoGa7 crystallizes in the tetragonal P-4m2 space group. La(1) is bonded in a 16-coordinate geometry to two equivalent Co(1), two equivalent Ga(3), two equivalent Ga(4), two equivalent Ga(5), four equivalent Ga(1), and four equivalent Ga(2) atoms. Co(1) is bonded to four equivalent La(1), four equivalent Ga(1), and four equivalent Ga(4) atoms to form distorted CoLa4Ga8 cuboctahedra that share corners with four equivalent Co(1)La4Ga8 cuboctahedra, corners with four equivalent Ga(5)La4Ga8 cuboctahedra, corners with eight equivalent Ga(3)La4Ga8 cuboctahedra, edges with two equivalent Ga(5)La4Ga8 cuboctahedra, faces with four equivalent Co(1)La4Ga8 cuboctahedra, and faces with four equivalent Ga(4)La4Ga4Co4 cuboctahedra. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent La(1), two equivalent Co(1), one Ga(2), and two equivalent Ga(4) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent La(1), one Ga(1), two equivalent Ga(3), and two equivalent Ga(5) atoms. In the third Ga site, Ga(3) is bonded to four equivalent La(1), four equivalent Ga(2), and four equivalent Ga(5) atoms to form distorted GaLa4Ga8 cuboctahedra that share corners with four equivalent Ga(4)La4Ga4Co4 cuboctahedra, corners with four equivalent Ga(3)La4Ga8 cuboctahedra, corners with eight equivalent Co(1)La4Ga8 cuboctahedra, edges with two equivalent Ga(4)La4Ga4Co4 cuboctahedra, faces with four equivalent Ga(3)La4Ga8 cuboctahedra, and faces with four equivalent Ga(5)La4Ga8 cuboctahedra.
