magnetostructural-driven analysis revealed a weak ferromagnetic interaction between the copper(II) ions within the N3–-bridged chains, complemented by an antiferromagnetic interaction between the chains mediated by π–π interactions. A survey of the scarce literature of single end-to-end azido bridges, associated with quantum chemical ab initio calculations, was carried out to tentatively identify the relevant
通过结合叠氮化物和 (Z)-1,1,1-trifluoro-4-(quinolin-8-ylamino)but-3-en-2-one enaminone 配体, HL, 叠氮桥铜 (II) 一维聚合物是在一锅反应中合成的。解析和精制的晶体结构证明了叠氮离子不寻常的单一和不对称端到端配位模式。通过循环伏安法研究了该配合物的氧化还原性质,证明了叠氮桥的氧化。磁性测量与磁结构驱动分析相结合,揭示了 N3-桥链内铜(II)离子之间的弱铁磁相互作用,辅以由 π-π 相互作用介导的链之间的反铁磁相互作用。对与量子化学 ab initio 计算相关的单端对端叠氮桥的稀缺文献的调查,
