X-ray and 1H, 13C and 15N NMR study of Au(III) chloride compounds with 7,8-benzoquinoline. [Display omitted] Au(III) chloride compounds with 7,8-benzoquinoline (bqn) – [Au(bqn)Cl3] and [Au(bqn∗)Cl2] (bqn∗ being deprotonated, at the C(10) carbon, monoanionic form of bqn) were studied by 1H–13C, 1H–15N HMQC and HMBC–NMR. 1H, 13C and 15N coordination shifts were discussed in relation to the molecular structures, revealing characteristic variability patterns. Analogous NMR measurements were performed for the new (bqnH+)2(AuCl4−)Cl− salt, studied also by single crystal X-ray diffraction. All compounds exhibited fluorescence.
