The diffraction data for L ligand and complex 1 were collected on a Bruker AXS P4 diffractometer [8] at 22 °C while those of 2 on a Bruker AXS SMART-1000 diffractometer [9] at 22 °C, respectively, which was equipped with a graphite-monochromated Mo Kα (λα = 0.71073 Å) radiation. Data reduction was carried by standard methods with use of well-established computational procedures. The structure factors were obtained after Lorentz and polarization correction. An empirical absorption correction based on a series of ψ-scans was applied to the data for L ligand and complex 1, while the empirical absorption correction based on "multi-scan" was applied to the data for complex 2. The positions of some of the heavier atoms, including the zinc atom, were located by the direct method. The remaining atoms were found in a series of alternating difference Fourier maps and least-square refinements [10]. All the hydrogen atoms were added by using the HADD program in SHELXTL 5.10.
