| 摘要: 采用具有手性的半胱氨酸衍生物配体,L-硫代脯氨酸(LTP)分别和高氯酸钴、高氯酸锰反应得到二维的化合物[Co(LTP)2]n (1) 和[Mn(LTP)2]n (2)。用X-射线衍射对这两个化合物的晶体结构进行了测定,结果表明其组成比列皆为1个金属离子和2个配体。磁性测定表明此两个化合物中金属离子之间有弱的反铁磁相互耦合作用。 |

| Abstract: An antiferromagnetic complexes based on Co(II) or Mn(II) and chiral ligand (L)-thioproline (LTP) with formula of [Co(LTP)2]n (1) and [Mn(LTP)2]n (2) were synthesized and structurally characterized. Single-crystal structures show that the complexes are formed by one metal ion and two ligands. Magnetic measurements show that a weak antiferromagnetic coupling occurs in the complexes.
