Ba(AuP2)2 crystallizes in the orthorhombic Fddd space group. Ba(1) is bonded in a 10-coordinate geometry to six equivalent Au(1) and four equivalent P(1) atoms. Au(1) is bonded in a 2-coordinate geometry to three equivalent Ba(1) and two equivalent P(1) atoms. P(1) is bonded in a 4-coordinate geometry to one Ba(1), one Au(1), and two equivalent P(1) atoms.
Ba(AuP2)2 crystallizes in the orthorhombic Fddd space group. Ba(1) is bonded in a 10-coordinate geometry to six equivalent Au(1) and four equivalent P(1) atoms. There are four shorter (3.39 Å) and two longer (3.66 Å) Ba(1)-Au(1) bond lengths. All Ba(1)-P(1) bond lengths are 3.51 Å. Au(1) is bonded in a 2-coordinate geometry to three equivalent Ba(1) and two equivalent P(1) atoms. Both Au(1)-P(1) bond lengths are 2.36 Å. P(1) is bonded in a 4-coordinate geometry to one Ba(1), one Au(1), and two equivalent P(1) atoms. There is one shorter (2.19 Å) and one longer (2.22 Å) P(1)-P(1) bond length.
