摘要：

The cyano(ergothionine)gold(I) complex, ErS-Au-CN was prepared and characterized by elemental analysis, IR and NMR spectroscopies. Its disproportionation in solution forming [Au(CN)(2)](-) and [(ErS)(2)Au](+) was investigated by C-13 and N-15 NMR. Equilibrium constant (K-eq) for disproportionation of the complex was measured by integrating the C-13 NMR at 297 K and was found to be 1.08. (C) 2001 Published by Elsevier Science B.V.
