The material described by CeOsGa4 crystallizes in the orthorhombic Pmma space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 10-coordinate geometry to one Ga(2), one Ga(6), two equivalent Ga(1), two equivalent Ga(3), two equivalent Ga(4), and four equivalent Ga(5) atoms. In the second Ce site, Ce(2) is bonded in a 16-coordinate geometry to four equivalent Os(1), two equivalent Ga(1), two equivalent Ga(6), four equivalent Ga(4), and four equivalent Ga(5) atoms. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded in a 8-coordinate geometry to two equivalent Ga(2), two equivalent Ga(3), and four equivalent Ga(5) atoms. In the second Os site, Os(1) is bonded in a 8-coordinate geometry to two equivalent Ce(2), two equivalent Ga(3), two equivalent Ga(4), two equivalent Ga(5), and two equivalent Ga(6) atoms. There are six inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to two equivalent Ce(2), four equivalent Ce(1), two equivalent Ga(4), and four equivalent Ga(5) atoms to form face-sharing GaCe6Ga6 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to two equivalent Ce(1), two equivalent Os(2), two equivalent Ga(6), and four equivalent Ga(5) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to two equivalent Ce(1), one Os(2), two equivalent Os(1), one Ga(3), two equivalent Ga(5), and two equivalent Ga(6) atoms. In the fourth Ga site, Ga(4) is bonded in a 5-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), two equivalent Os(1), and one Ga(1) atom. In the fifth Ga site, Ga(5) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), one Os(1), one Os(2), one Ga(1), one Ga(2), one Ga(3), and one Ga(6) atom. In the sixth Ga site, Ga(6) is bonded in a 10-coordinate geometry to one Ce(1), one Ce(2), two equivalent Os(1), one Ga(2), one Ga(6), two equivalent Ga(3), and two equivalent Ga(5) atoms. is represented by the CIF card [CIF]
