meso-1,2-bis(ethylsulfinyl)ethane (meso-L) with Ln(ClO(4))(3) [Ln(NO(3))(3) or Ln(NCS)(3)] in MeOH and CHCl(3) gave a series of new lanthanide coordination polymers, [[Ln(micro-meso-L)(rac-L)(2)(CH(3)OH)(2)](ClO(4))(3)](n) [Ln: La (1), Nd (2), Eu (3), Gd (4), Tb (5), Dy (6), and Yb (7)], [Yb(micro-meso-L)(1.5)(NO(3))(3)](n) (8), and [La(micro-meso-L)(2.5)(NCS)(3)](n) (9). All the structures were established
Meso-1,2-双(乙基亚磺酰基)乙烷(meso-L)与Ln(ClO(4))(3)[Ln(NO(3))(3)或Ln(NCS)(3)]的反应在MeOH和CHCl(3)中制得一系列新的镧系配位聚合物[[Ln(micro-meso-L)(rac-L)(2)(CH(3)OH)(2)](ClO(4) )(3)](n)[Ln:La(1),Nd(2),Eu(3),Gd(4),Tb(5),Dy(6)和Yb(7)],[Yb (micro-meso-L)(1.5)(NO(3))(3)](n)(8)和[La(micro-meso-L)(2.5)(NCS)(3)](n) (9)。通过单晶X射线衍射确定所有结构。配合物1-7是具有无限单微链结构的同构结构,其中L配体采取两种配位模式:双齿螯合和双单齿桥联。每个Ln(III)中心周围的亚砜基团的六个硫原子在链中交替采用相同的R或S构型。此外,与Ln(ClO(4))(
