Abstract

A cobalt coordination polymer with the formula of {[Co(L¹)(pa)]}_n (1) (L¹ = bis(4-(1H-benzo[d]imidazol-1-yl)phenyl)methanone, H₂pa = phthalic acid) was synthesized under solvothermal condition. It was characterized by infrared spectroscopy, elemental and single-crystal X-ray diffraction analyses. Crystal 1 is monoclinic, the space group is P2₁/c with the unit cell parameters a = 8.1394(2), b = 25.7199(5), c = 15.1719(4) Å, β = 117.554(2)°, Z = 4; R₁ = 0.0405 and wR₂ = 0.0953 (I > 2σ). In 1, [Co₂(pa)₂] bridged by pa^2– anions are linked by four adjacent L¹ ligands and form 2D layers.

摘要

式为{[Co（L ¹）（pa）]} _n（1）的钴配位聚合物（L ¹ =双（4-（1 H-苯并[ d ]咪唑-1-基）苯基]甲酮，在溶剂热条件下合成H ₂ pa =邻苯二甲酸。通过红外光谱，元素和单晶X射线衍射分析对其进行表征。晶体1为单斜晶，空间群为P 2 ₁ / c，晶胞参数a = 8.1394（2），b = 25.7199（5），c = 15.1719（4）Å，β= 117.554（2）°，Z = 4；R ₁ = 0.0405和wR ₂ = 0.0953（I >2σ）。在1中，由pa ^2–阴离子桥接的[Co ₂（pa）₂ ]通过四个相邻的L ¹配体连接并形成2D层。
