General Information: All the reagents were commercially available and used without further purification. Elemental (C, H and N) analyses were performed on a CE-440 (Leemanlabs) analyzer. Thermal gravimetric analysis (TGA) was performed on a PerkinElmer TGA 7 instrument in the temperature range of 25-700°C at a heating rate of 10°C/min under air atmosphere. IR spectra were recorded as KBr pellets on a FTIR-8400 spectrometer in the range of 4000-400 cm-1. The single-crystal X-ray structures were determined on a Bruker Smart APEX CCD area detector. Powder X-ray diffraction (PXRD) data were recorded on a Rigaku D/Max-2500 diffractometer at 40 kV and 30 mA for a Cu-target tube. The calculated PXRD patterns were produced from the single-crystal diffraction data using the diamond software.

Crystal structure determination of 1 and 2: Single-crystal X-ray diffraction was performed using a Bruker Apex II CCD diffractometer equipped with a fine-focus sealed-tube X-ray source (Mokα radiation, graphite monochromated). Structures were solved by direct methods using SHELXTL and were refined by full-matrix least-squares on F2 using SHELX-97. Non-hydrogen atoms were refined with anisotropic displacement parameters during the final cycles. Hydrogen atoms were placed in calculated positions with isotropic displacement parameters set to 1.2×Ueq of the attached atom.
