Ce2PdGa7 crystallizes in the tetragonal P4mm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 16-coordinate geometry to four equivalent Pd(1), four equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(5) atoms. In the second Ce site, Ce(2) is bonded in a 16-coordinate geometry to four equivalent Ga(1), four equivalent Ga(2), four equivalent Ga(3), and four equivalent Ga(4) atoms. Pd(1) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Ga(5), and four equivalent Ga(1) atoms. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Ce(1), two equivalent Ce(2), two equivalent Pd(1), and two equivalent Ga(4) atoms. In the second Ga site, Ga(2) is bonded to two equivalent Ce(1), two equivalent Ce(2), two equivalent Ga(3), two equivalent Ga(5), and four equivalent Ga(2) atoms to form a mixture of distorted face and corner-sharing GaCe4Ga8 cuboctahedra. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to four equivalent Ce(2), one Ga(4), and four equivalent Ga(2) atoms. In the fourth Ga site, Ga(4) is bonded in a 9-coordinate geometry to four equivalent Ce(2), one Ga(3), and four equivalent Ga(1) atoms. In the fifth Ga site, Ga(5) is bonded in a distorted single-bond geometry to four equivalent Ce(1), one Pd(1), and four equivalent Ga(2) atoms.
