Preliminary studies of three isostructural compounds with the formula [Ln(DMSO)4(H2O)2(Au(CN)2)2]Au(CN)2 (Ln = Eu, Gd, Tb), abbreviated LnDMSOAu, were performed. Crystal structures and Au-Au distances were determined with X-Ray diffraction. Both [Au(CN)2]- and DMSO within LnDMSOAu have the potential to transfer energy to the lanthanide, although the studies are focused on the contribution from the cyanometallate system. Such potential was studied via photoluminescence experiments with two foci. First, effect of DMSO on cyanometallate systems were drastic and were examined by comparing photoluminescence spectra with studies of Ln[Au(CN)2]●3H2O. Second, changes in those energy transfer with respect to changes in temperature were studied via temperature-dependent scans.
