Abstract

[Ni(HF(2))(3-Clpy)(4)]BF(4) (py = pyridine) is a simple one-dimensional (1D) coordination polymer composed of compressed NiN(4)F(2) octahedra that form chains with bridging HF(2)(-) ligands. In spite of significant distortion of the HF(2)(-) bridge, a quasi-1D antiferromagnetic (AFM) behavior was observed with J(FHF) = 4.86 K.

摘要

[Ni(HF(2))(3-Clpy)(4)]BF(4)（py = 吡啶）是一种由压缩的 NiN(4)F(2)八面体组成的简单一维（1D）配位聚合物，这些八面体通过桥连的 HF(2)(-)配体形成链。尽管 HF(2)(-)桥存在显著的扭曲，但观察到准一维反铁磁（AFM）行为，J(FHF) = 4.86 K。
