    • Synthesis of 1: To a solution of (NH4)2MoO4 (0.2 mmol, 0.038 g) in 10 mL water was added imi (1.0 mmol, 0.068 g, after stirred vigorously for 20 min, the mixed system was transferred into a 23 ml Teflon-lined stainless steel autoclave, sealed and heated inside a furnace to 150 °C for three days, then slowly cooled to room temperature at a rate of 5 °C per an hour. Finally, colorless block crystals of 1 were recovered by filtration in approximate 85% yield based on (NH4)2MoO4. Anal. Calcd. for C12H16Mo2N8O6, C, 25.73; H, 2.88; N, 20.00; Found: C, 25.80; H, 2.85; N, 19.95. FT-IR cm-1, KBr, 3451 s, 3067 w, 3028 w, 1627 w, 1604 s, 1573 w, 1490 m, 1448 s, 1363 w, 1241 w, 1221 m, 1153 w, 1079 m, 1043 m, 1016 m, 944 m, 867 w, 756 s, 688 s, 441 w, 597 s. The characteristic band at 944 cm-1 in FTIR spectrum is due to the Mo{double bond, lo
    • -1 in FTIR spectrum is due to the Mo{double bond, long}O stretching mode, and indicates the presence of the terminal Mo{double bond, long}O group.

A total of 5601 reflections were collected, of which 2049 (Rint, 0.0180) were unique. Intensity data were collected on a Bruker SMART CCD diffractometer equipped with a graphite-monochromated Mo Kα radiation (λ, 0.71073 Å) at 293(2) K using the ω-2θ scan technique. The structure was solved by direct methods and refined by full-matrix least-squares fitting on F2 by SHELXTL-97.
