近年来，金属有机配位聚合物由于其独特的电学、磁学、催化和光学性能而受 到普遍关注。通过选择不同的多齿配体和金属离子，可以组装成具有各处新型骨架 结构和特殊物理化学性能的配位聚合物。异烟酸根可以通过吡啶环氮原子和羧基氧 原子与金属离子配位，生成配位聚合物。本文采用三氯化铁和4-氰基吡啶在水热条 件下的反应可控地合成具有三维骨架结构的配位聚合物[Fe(C_5H_4NCOO)_2]_n，并 进行元素分析、红外光谱表征，单晶结构测定和UV-VIS-NIR（紫外-可见-近红外） 反射光谱研究。

A novel coordination polymer. [Fe(C_5H_4NCOO)_2]_n, was synthesized by hydrothermal reaction and characterized by elemental analysis as well as IR spectroscopy. The crystal structure (with a novel 3-D network) of this compound belongs to monoclinic, space group P2_1/N, A = 0.49544(1) nm, b = 1.32443(2) nm, c = 1.04983(1) nm, β = 101.586(1) °. The diffuse reflectance spectra (200～2500 nm) showed that the polymer had strong absorbance in 375～563 nm (E_g ≈ 2.5 eV) region and weak absorbance from 720 to 2500 nm (near infrared spectra).
