    • The data presented here were the original ones without the mass calibration. Commonly, the acceptable accuracy range of the HRMS spectra to characterize the compound structure should be under 10 mmu (millimass units, However, under the test concentration (10 μM, the signal was comparatively weak and easily disturbed by the environment, which caused it to be hard to calibrate, and consequently, the acceptable error increased to as high as 200 mmu. In addition, the HRMS test was also tried under a fluorescence spectra test situation-ethanol-water solutions (1:9, v/v, 50 mM HEPES buffer, pH, 7.2) and [1a, Zn2, 10 μM-but it failed to get satisfactory results due to the great impact of the high concentration of HEPES. The data were measured on Q-Tof Micro Micromass Inc, Manchester, England, using ESI as the ion source. In addition, HRMS did not detect the existence of [1a, Cd2, H, species
