A helicate gold triphos triflate ([Au3(Triphos)2](OTf)3, Triphos = PPh(CH2CH2PPh2)2) complex first crystallized by Schuh et. al (2001) is examined for its interesting luminescent properties.  Reactions with halides produced bridged helicate dimer complexes with distinct differences in luminescence.  These bridged complexes display the capacity for rearrangements into hexagold complexes [Au6Cl(Triphos)4]5+ with identical stoichiometry.  The role of anions in stabilizing the salt [Au6Cl(Triphos)4](SbF6)5 will be discussed.
