The material described by CeFe5Ga7 crystallizes in the orthorhombic Imm2 space group. Ce(1) is bonded in a 20-coordinate geometry to two equivalent Fe(2), eight equivalent Fe(1), one Ga(1), one Ga(2), two equivalent Ga(3), two equivalent Ga(4), and four equivalent Ga(5) atoms.

There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Ce(1), four equivalent Fe(1), one Ga(2), two equivalent Ga(4), and two equivalent Ga(5) atoms.
