摘要：

Three new cyano-bridged complexes 1 [Ni(tn)(2)Ni(CN)(4)] (tn = 1,3-diaminopropane), 2 [Cu-II(dipn)Ni-II(CN)(4)], and 3 [Cu(dipn)](6)[Co(CN)(6)](4) 4H(2)O (dipn = dipropylenetriamine) have been assembled by the templates [Ni(CN)(4)](2-) and [Co(CN)(6)](3-). 1 consists of a one-dimensional linear chain-Ni(tn)(2)-NC-Ni(CN)(2)-CN-Ni(tn)(2-) in which the Ni(II) centers are linked by two CN groups. One 1-D zigzag chain of 2 is formed with-Ni(2)-C-N-Cu(1)-N-C-linkages. A 2D structure of 3 is formed by an alternate array of [Co(CN)(6)](3-) and [Co][Cu-6] units. For 1, there is an overall weak antiferromagnetic interaction between Ni(II) ions through the-NC-Ni-CN-bridges of the diamagnetic [Ni(CN)(4)](2-) anions. 2 exhibits a weak antiferromagnetic exchange interaction between copper(II) ions mediated by [Ni(CN)(4)](2-) diamagnetic bridges. Complex 3 exhibits a weak ferromagnetic interaction between nearest CuII and CuII atoms through-NC-Co-CN-bridges.
