Three new metal coordination polymers [Ni(μ-L)(HO)] (1, HL = 1-tetrazole-4-imidazole-benzene), [Co(μ-L)] (2), and [Co(μ-OH)(μ-Cl)(μ-L)(μ-L)] ·7HO (3) were hydrothermally synthesized and structurally characterized. 1 displays a neutral [Ni(μ-L)(HO)] chain built up from the Ni ions bridged by deprotonated L ligands, while 2 shows another rare neutral [Co(μ-L)] chain based on Co ions connected by two different coordination modes of the L ligand. 3 exhibits a rare [Co(μ-OH)(μ-Cl)] mixed oxo-chloro-cluster-based three-dimensional framework with large elliptical channels, which are filled by unprecedented chilopod [(HO)] chains. Both 1 and 2 show antiferromagnetic behavior, while 3 exhibits unusual spin-canting.
通过水热法合成并对三种新型金属配位聚合物[Ni(μ-L)(H₂O)] (1, HL = 1-四唑-4-咪唑苯)、[Co(μ-L)] (2)和[Co(μ-OH)(μ-Cl)(μ-L)(μ-L)] ·7H₂O (3)进行了结构表征。1呈现出由去质子化的L配体桥连的Ni离子构成的中性[Ni(μ-L)(H₂O)] 链，而2展示了另一种基于L配体的两种不同配位模式连接的Co离子的罕见中性[Co(μ-L)] 链。3呈现出一种罕见的基于[Co(μ-OH)(μ-Cl)]混合氧氯簇的三维框架，具有大的椭圆形通道，通道中填充有前所未有的千足虫状[(H₂O)] 链。1和2均表现出反铁磁行为，而3表现出不寻常的自旋倾斜。
