在DMF-H2O介质中，通过（n-Bu 4 N）3Fe（CN）6与Sm（NO3）3·6 H2O反应，合成了一种新型的氰基桥联的SmIII-FeIII 3配位聚合物.该配合物由Sm（DMF）4（H2O）2和Fe（CN）6单元交替组成，并由两个顺式氰基配体桥接形成锯齿形链状结构。它的行为就像一个基于分子的磁铁，Tc = 3.4 K。在2K下，在200 Oe的矫顽场下观察到滞后。
A new cynao-bridged Sm I I I -Fe I I I bimetallic coordination polymer has been prepared by the reaction of (n-Bu 4 N) 3 Fe(CN) 6 and Sm(NO 3 ) 3 .6H 2 O in a DMF-H 2 O media. The complex consists of alternate Sm(DMF) 4 (H 2 O) 2 and Fe(CN) 6 units bridged by two cis-cyano ligands to form a zigzag chain. It behaves as a molecule-based magnet with T c = 3.4 K. At 2K, hysteresis was observed with a coercive field of 200 Oe.
