The Materials Project

K2Au3 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. K is bonded in a 8-coordinate geometry to ten Au atoms. There are a spread of K–Au bond distances ranging from 3.43–3.99 Å. There are two inequivalent Au sites. In the first Au site, Au is bonded to eight equivalent K and four equivalent Au atoms to form a mixture of distorted face and edge-sharing AuK8Au4 cuboctahedra. All Au–Au bond lengths are 2.86 Å. In the second Au site, Au is bonded in a 10-coordinate geometry to six equivalent K and four Au atoms. There are one shorter (2.75 Å) and one longer (2.85 Å) Au–Au bond lengths.
