| 摘 要： | Two macrocyclic zinc(II) complexes {ZnL(VO3)2]·0.33H2O}n(1) and ZnL(H2O)2]Ni(CN)4](2)(L = 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane) have been obtained from the reactions of ZnL](ClO4)2 with NH4VO3 and K2Ni(CN)4], respectively, and structurally characterized by elemental analysis, IR, XRPD, TG and X-ray diffraction. Single-crystal X-ray diffraction analyses indicated that the Zn(II) atom lies on an inversion center and is octahedrally coordinated by four nitrogen atoms of the tetradentate macrocyclic ligand in the equatorial plane and two oxygen atoms of VO4] tetrahedra in the axial positions in 1, and two oxygen atoms of two water molecules in 2. Complex 1 shows a three-dimensional structure, which is constructed by the links of VO3]nn- chains with ZnL]2+, forming one-dimensional channels occupied by guest water molecules. The monomers of ZnL(H2O)2]2+ and Ni(CN)4]2- are connected through the intermolecular hydrogen bonds to form a two-dimensional sheet in complex 2.
