The pyrazole-based diamide ligand N,N'-bis(2-pyridylmethyl)pyrazole-3,5-dicarboxamide (H(3)L) has been structurally characterised and successfully employed in the preparation of [2 x 2] grid-type complexes. Thus, the reaction of H(3)L with Cu(ClO(4))2.6H(2)O or Ni(ClO(4))2.6H(2)O in the presence of added base (NaOH) affords the tetranuclear complexes [M(4)(HL(4))].8H(2)O (1: M = Cu, 2: M = Ni).

吡唑基二酰胺配体N,N'-双(2-吡啶基甲基)吡唑-3,5-二甲苯酰胺(H(3)L)在结构上已得到表征,并成功用于制备[2 x 2]网格型复合体。因此,H(3)L与Cu(ClO(4))2.6H(2)O或Ni(ClO(4))2.6H(2)O在添加的碱(NaOH)存在下的反应得到四核配合物[M(4)(HL(4))]。8H(2)O(1:M = Cu,2:M = Ni)。在其他相同的反应条件下使用两种金属盐的混合物会导致形成混合金属物质[Cu(x)Ni(4-x)(HL)(4)]。8H(2)O(x
