制备了具有三吡啶型配体的钴（ii）配合物[Co(n-pyterpy)2](ClO4)2 (n = 3（1), 4(2)）。三吡啶配体中氮原子的不同位置影响其在晶体结构中的组装性能。配合物1显示出由分子间N⋯HC相互作用连接的1D链组成的二维网络结构。另一方面，配合物2由两个不同的钴离子位点（Co1和Co2）组成，配位环境略有不同。配合物2为一维链，无链间相互作用。讨论了这些差异，并用自旋交叉行为估计了它们的合作度。
Cobalt(ii) complexes with terpyridine-type ligands, [Co(n-pyterpy)2](ClO4)2 (n = 3 (1), 4 (2)), were prepared and characterised. Different positions of the nitrogen atom in the terpyridine ligands influenced their assembly properties in the crystal structures. Complex 1 showed a 2D network structure consisting of 1D chains connected by intermolecular N⋯HC interactions. On the other hand, complex 2 consisted of two different cobalt ion sites (Co1 and Co2) with slightly different coordination environments. Complex 2 showed 1D chains with no interchain interactions. Such differences are discussed with the cooperativities estimated by their spin crossover behaviours.
