A novel, three-coordinate gold(I) dimer, Au2(tfepm)3Cl2 (la, lb), was synthesized and structurally characterized. Four gold(I)-rhodium(I) heterobimetallic complexes, AuIRh'(tBuNC)2(-dppm)2C12 (2), Au'Rh'(tBuNC)2(u-dmpm)2Cl2 (3), Au'Rh'(tBuNC)2(,u-tfepm)2C12 (4), and AuIRh(tBuNC)2(u-tfepma)2Cl2 (5) were synthesized and 2, 3, and 5 were crystallographically characterized. Absorption spectra at room temperature, excitation spectra, emission spectra, and phosphorescence lifetimes of glass-solution and solid state samples at 77 K are reported for 2-5 and interpreted in context of crystallographic structure, electronic structure, and time-dependent density functional theory (TD-DFT) calculations. 2-5 are intensely luminescent at 77 K, with 4 and 5 exhibiting "dual emission."

<Abstract>A novel, three-coordinate gold(I) dimer, Au2(tfepm)3Cl2 (la, lb), was synthesized and structurally characterized. Four gold(I)-rhodium(I) heterobimetallic complexes, AuIRh'(tBuNC)2(-dppm)2C12 (2), Au'Rh'(tBuNC)2(u-dmpm)2Cl2 (3), Au'Rh'(tBuNC)2(,u-tfepm)2C12 (4), and AuIRh(tBuNC)2(u-tfepma)2Cl2 (5) were synthesized and 2, 3, and 5 were crystallographically characterized. Absorption spectra at room temperature, excitation spectra, emission spectra, and phosphorescence lifetimes of glass-solution and solid state samples at 77 K are reported for 2-5 and interpreted in context of crystallographic structure, electronic structure, and time-dependent density functional theory (TD-DFT) calculations. 2-5 are intensely luminescent at 77 K, with 4 and 5 exhibiting "dual emission."</Abstract>
