The crystal of 1 crystallizes in monoclinic, space group C2/c with a = 24.513（8）, b = 18.948（5）, c = 17.248（6）, β = 119.81（2）o, V = 6951（4）3, Z = 8, C40H30Cu2N8O8, Mr = 877.80, Dc = 1.678 g/cm3, F（000） = 3584 and μ（MoKα） = 1.295 mm-1. The final R = 0.0542 and wR = 0.1335 for 5398 observed reflections with I 〉 2σ（I） and R = 0.0845 and wR = 0.1520 for all data. X-ray diffraction analysis reveals that the title complex is a unique ＇three-in-one＇ crystal of coordination network through strong hydrogen bonds and coordination covalent bonds. The thermogravimetric analysis measurement showed that compound 1 has thermal stability as no strictly clean weight loss step occurs below 300 ℃.展开更多
