Gold(I) complex cations of empirical formula
Au[Ph2P(CH2)nPPh2
]+ crystallize as rings
[Au2Ph2P(CH2)n
PPh2}2]2+ when
n = 3 or 5 but as a polymer
[Au[Ph2P(CH2)nPPh2
]}x]x+ when n =
4. In favorable cases, the ring complexes can be connected through
aurophilic bonding by addition of [Au(CN)2]−,
and crystals contain pentagold units when n = 3 or polymeric
pleated chains when n = 5.
