    • Compound 1 was synthesized as follows: H2L (0.10 g, 0.23 mmol) and Hg(NO3)2·0.5H2O (0.08 g, 0.23 mmol) were mixed and stirred in 20 mL of CH3OH for 2 h at room temperature, with a red solution forming. After careful evaporation of the solution in air for a few days, orange crystals with a prism shape were formed. Anal. Calcd for Hg2C47H40N18O 8S2: C, 38.93; H, 2.78; N, 17.38.

The intensities of compound 1 were collected on a Siemens SMART CCD diffractometer with graphite-monochromated Mo Kα (λ, 0.710 73 Å) using the SMART and SAINT programs; 4929 unique reflections were collected for 3388 reflections with I > 2σI, The structure was solved by direct methods and refined on F2 by full-matrix least-squares methods with SHELXTL version 5.1. All of the non-H atoms were refined anisotropically

    • The compound HL was synthesized as follows: The mixture of H2L1 (0.44 g, 1 mmol) and Hg(NO3) 2·0.5H2O (0.33 g, 1 mmol) in 40 mL of CH 3OH were refluxed for 6 h. Upon the addition of 1.2 mL of NH 4S (8% aqueous solution) and further stirring for 4 h, a dark precipitate formed and was filtered off. The crude product that was obtained by evaporating the filtration under reduced pressure was chromatographed on silica gel with a CH2Cl2/MeOH (1:1) solution as the eluent.
