摘要

Two supramolecular complexes, [Ni(rac-L)]3[CrO4]2[ClO4]2.4H2O (1) and [meso-H2L]0.5[VO3].0.16H2O (2) (L=5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetra-decane), have been prepared in an aqueous solu-tion, and detected by elemental analysis, IR, TG, and single crystal X-ray diffraction analyses. Com-pound 1 shows a one-dimensional hexagonal prism formed by the hydrogen bonding interactions be-tween the secondary amines of rac-L and CrO42- anion/water molecules. Compound 2 displays a three-dimensional structure constructed by the hydrogen bond linking the helical chains of [VO3]nn- to the secondary amines of meso-L to generate 1D hexagon-shaped channels, and the channels are oc-cupied by guest water molecules.
