Au3P is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Au(1) is bonded to eight equivalent Au(1) and four equivalent P(1) atoms to form distorted AuP4Au8 cuboctahedra that share corners with four equivalent P(1)Au12 cuboctahedra, corners with fourteen equivalent Au(1)P4Au8 cuboctahedra, edges with six equivalent P(1)Au12 cuboctahedra, edges with twelve equivalent Au(1)P4Au8 cuboctahedra, faces with four equivalent P(1)Au12 cuboctahedra, and faces with sixteen equivalent Au(1)P4Au8 cuboctahedra. P(1) is bonded to twelve equivalent Au(1) atoms to form PAu12 cuboctahedra that share corners with six equivalent P(1)Au12 cuboctahedra, corners with twelve equivalent Au(1)P4Au8 cuboctahedra, edges with eighteen equivalent Au(1)P4Au8 cuboctahedra, faces with eight equivalent P(1)Au12 cuboctahedra, and faces with twelve equivalent Au(1)P4Au8 cuboctahedra.

There are a spread of Au(1)-Au(1) bond distances ranging from 2.90-3.03 Å. There are two shorter (2.87 Å) and two longer (2.98 Å) Au(1)-P(1) bond lengths. P(1) is bonded to twelve equivalent Au(1) atoms to form PAu12 cuboctahedra that share corners with six equivalent P(1)Au12 cuboctahedra, corners with twelve equivalent Au(1)P4Au8 cuboctahedra, edges with eighteen equivalent Au(1)P4Au8 cuboctahedra, faces with eight equivalent P(1)Au12 cuboctahedra, and faces with twelve equivalent Au(1)P4Au8 cuboctahedra.
