BaGa2P2 is Calaverite-derived structured and crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 6-coordinate geometry to three equivalent P(1) and three equivalent P(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 3-coordinate geometry to one P(1) and two equivalent P(2) atoms. In the second Ga site, Ga(2) is bonded in a 3-coordinate geometry to one P(2) and two equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to three equivalent Ba(1), one Ga(1), and two equivalent Ga(2) atoms to form a mixture of distorted corner and edge-sharing PBa3Ga3 octahedra. The corner-sharing octahedral tilt angles range from 23-100°. In the second P site, P(2) is bonded to three equivalent Ba(1), one Ga(2), and two equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing PBa3Ga3 octahedra. The corner-sharing octahedral tilt angles range from 22-100°.
BaGa2P2 is Calaverite-derived structured and crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 6-coordinate geometry to three equivalent P(1) and three equivalent P(2) atoms.
