A heart of gold : The reaction of silylated arsenic derivatives with gold( I ) phosphine complexes produces gold–arsenic clusters, such as [Au 19 (As n Pr) 8 (dppe) 6 ] 3+ (dppe=Ph 2 P(CH 2 ) 2 PPh 2 ). This complex cation (see picture; Au gold, As blue, P violet) can be described as two crossing Au 9 As 4 chains (red and green), and contains a gold octahedron centered by a gold atom.
