Two copper-nickel complexes, {[Cu(i-Pr3TACN)][Ni(CN)4]}2·2H2O (1) and {[Cu(DACH)][Ni(CN)4]}n (2), have been synthesized by the self-assembly reactions of K2[Ni(CN)4] with CuCl2 and the corresponding chelating ligand 1,4,7-triisopropyl-1,4,7- triazacyclononane (i-Pr3TACN) or 1,4-diazacycloheptane (DACH), respectively. The complexes were structurally characterized by single-crystal X-ray diffraction, elemental analyses, IR spectra and magnetic properties. Complex 1 presents a [2+2] type of molecular square structure and 2 features a 2D β-pucker structure. The magnetic susceptibility measurements reveal a weak antiferromagnetic interaction between the Cu(Ⅱ) ions, with the J values of-22.11 and -32.50 cm-1 for 1 and 2. Moreover, by changing the size of macrocyclic ligands we have successfully constructed two different strictures, which may provide useful information for the construction of the structure.
