摘要：

The synthesis of triethylphosphine gold(I) 4-nitrobenzenethiolate, Et3PAu(SC6H4NO2-4), is reported. Et3PAu(SC6H4NO2-4) displays a low energy visible electronic absorption band which is solvent dependent: EtOH (lambda(max) = 385 nm), acetonitrile (lambda(max) = 391 nm), THF (lambda(max) = 395 nm), and DMSO (lambda(max) = 402 nm). The corresponding low energy visible electronic absorption band of 4-nitrobenzenethiolate, 4-NO2C6H4S also shows solvent dependency: acetonitrile, (lambda(max) = 484 nm), DMSO (lambda(max) = 502 nm), dimethylformamide (lambda(max) = 505 nm). The positive solvatochromic shifts for Et3PAu(SC6H4NO2-4) and 4-NO2C6H4S are consistent with an intraligand (IL) charge transfer transition, i.e. pi(S) ->*pi (C6H4NO2-4) or n(S) -> *pi (C6H4NO2-4). Assignment of 4-NO2C6H4S was aided by a DFT calculation. (C) 2009 Elsevier B. V. All rights reserved.
