4·2CH2Cl2, 2.9288(9)–3.0514(10) Å in 5·2CH2Cl2·H2O, and 2.9236(12)–3.1914(17) Å in 6, implying significant aurophilic interactions. These gold(I) complexes exhibit intense photoluminescence properties in solid state. Upon lowering the temperature from 298 to 77 K, complexes 5 and 6 exhibit an obvious red-shift from 536 nm to 589 nm for 5 and from 538 nm to 564 nm for 6, implying significant luminescence
