A heart of gold: The reaction of silylated arsenic derivatives with gold(I) phosphine complexes produces gold–arsenic clusters, such as [Au19(AsnPr)8(dppe)6]3+ (dppe=Ph2P(CH2)2PPh2). This complex cation (see picture; Au gold, As blue, P violet) can be described as two crossing Au9As4 chains (red and green), and contains a gold octahedron centered by a gold atom.
