Abstract

A new 2D manganese(II) coordination polymer, namely [Mn(L)_0.5(2,2′-bipy)]_n·nH₂O (1), has been constructed hydrothermally based on manganese acetate and the mixed ligands including the 5.5′-(benzene)-1,4-diyl)-bis(oxy) diterphthalic acid (H₄L) and auxiliary 2,2′-bipyridine (2,2′-bipy). The compound was characterized by elemental analyses, was characterized by elemental analysis, infrared spectrum and single-crystal and powder X-ray diffractions, and thermal analyses. Single-crystal X-ray diffraction analyses revealed that compound 1 crystallize in the triclinic system, space group P-1. The adjacent Mn(II) ions are bridged by µ₆-L⁴⁻ ligands, producing a 2D layer. Magnetic studies for compound 1 demonstrate an antiferromagnetic coupling between the adjacent Mn(II) centers.

摘要

基于醋酸锰和包括5.5在内的混合配体，通过水热法构建了一种新的二维锰(II)配位聚合物，即[Mn(L) _0.5 (2,2'-bipy)] _n ·nH ₂ O ( 1 ) '-(苯)-1,4-二基)-双(氧基)二对苯二甲酸(H ₄ L)和助剂2,2'-联吡啶(2,2'-联吡啶)。该化合物通过元素分析表征，通过元素分析、红外光谱和单晶和粉末 X 射线衍射以及热分析表征。单晶 X 射线衍射分析表明，化合物1在三斜晶系、空间群 P-1 中结晶。相邻的 Mn(II) 离子由 µ ₆ -L ⁴⁻桥接配体，产生二维层。化合物1 的磁性研究表明相邻 Mn(II) 中心之间存在反铁磁耦合。
