    • A mixture of Nd2O3(0.067 g, 0.2 mmol, Cu(ClO4)2 (0.079 g, 0.3 mmol, and HL (0.116 g, 0.6 mmol) and oxalic acid (0.107, 1.2 mmol) was dissolved into a mixed solution of absolute ethanol (2 mL) and distilled water 10 mL, The resulting solution was stirred for about 1 h at room temperature, sealed in a 23-mL Teflon-lined stainless steel autoclave, and heated at 140 °C for 3 days under autogenously pressure, then; the reaction system was gradually cooled to room temperature. Blue crystals of 1 suitable for single-crystal X-ray diffraction analysis were collected from the final reaction system by filtration, washed several times with distilled water, and dried in air at ambient temperature. Yield: 45% based on Cu. Anal. Calcd for 1: C, 26.74; H, 2.52, N, 4.16. Found: C, 26.73; H, 2.50; N, 4.17

    • A blue crystal of 1 with a dimension of 0.150 mm × 0.120 mm × 0.108 mm was selected on a Bruker P4 diffractomerter with graphite-monochromated MoKα radiation λ, 0.71073 Å, at 293 K using the θ-2θ scan technique. The data were corrected for Lp and absorption effects. The crystal structure was solved by direct methods with the SHELXS-97 program. Subsequent difference Fourier syntheses enabled all heavier atoms to be located. After several cycles of refinement, all hydrogen atoms were located from the successive difference Fourier syntheses. All non-hydrogen atoms were finally refined with anisotropic displacement parameters by full-matrix least-squares techniques. The hydrogen atom positions were fixed geometrically at calculated distances and allowed to ride on the parent carbon atoms. CCDC NO, 744130 for 1
