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 between 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.

Compound 2 displays a three-dimensional structure constructed by the hydrogen bond linking the helical chains of [VO3] n n? to the secondary amines of meso-L to generate 1D hexagon-shaped channels, and the channels are occupied by guest water molecules.
