Ba3GaP3 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 8-coordinate geometry to two equivalent Ga(1), two equivalent P(2), and four equivalent P(1) atoms. In the second Ba site, Ba(2) is bonded in a 7-coordinate geometry to one Ga(1), one P(1), and five equivalent P(2) atoms. Ga(1) is bonded to two equivalent Ba(1), two equivalent Ba(2), two equivalent P(1), and two equivalent P(2) atoms to form distorted face-sharing GaBa4P4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to two equivalent Ba(2), four equivalent Ba(1), and two equivalent Ga(1) atoms. In the second P site, P(2) is bonded in a 7-coordinate geometry to one Ba(1), five equivalent Ba(2), and one Ga(1) atom.
