The synthesis of triethylphosphine gold(I) 4-nitrobenzenethiolate and solvent dependent visible absorption spectra of 4-nitrobenzenethiolate

The thiolate, 4-NO2C6H4S−, and gold(I) complex, R3PAu(SC6H4NO2-4) display positive solvatochromic shifts for the low energy visible electronic absorption bands as a function of solvent donor numbers.
