Complex 2 is of monoclinic system, space group C2/c with a = 16.7767（2）, b = 10.8989（2）, c = 17.4928（2） A, fl = 90.614（9）°, V= 3198.37 A3, Z = 4, C28H34N4O14Cd, Mr= 731.25, F（000） = 1528, Dc = 1.568 g＇cm^-3, μ（MoKa） = 0.757 mm-1, the final R = 0.0361 and wR = 0.0857 for 19811 observed reflections with I 〉 2σ（I）. The two complexes were formed by Schiff base 2-methoxy-6-（phenyliminiomethyl） phenolate ligand and formed a 3D supramolecular architecture by π-πstacking interactions. Moreover, the complexes are luminescent in the solid state. These observations indicate that the complexes are promising system for the development of potential photoactive materials.展开更多

The crystal is of monoclinic, space group P21/c with a =11.169(3), b = 9.508(3), c = 17.690(5) ? b = 91.593(5), Z = 4, V = 1877.9(10) 3, Dc = 1.459 g/cm3, F(000) = 856, m(MoKa) = 0.324 mm-1, R = 0.0690 and wR = 0.1368 for 3301 observed reflections (I > 2s(I)). The N(1)H…N(3) and N(2)H…O(4) hydrogen bonds can be observed. In the molecule the phenyl plane(I), pyrimi- din-2-yl-urea bridge plane(Ⅱ) and ester plane(Ⅲ) form three conjugated systems.展开更多

The structure of the new compound was established on the basis of various NMR spectroscopic analyses including 2D NMR techniques, El-MS, and HR-ESI-MS. This compound displayed moderate antifungal activity.展开更多
