资源简介:
Five heterometallic 3d–4f coordination polymers based on 1,4,7-triazacyclononane-1,4,7-triyl-tris­(methylenephosphonic acid) (notpH6) are reported. Compounds [FeLn­(notpH)­(H2O)4]­ClO4·5H2O [Ln = Nd (FeNd), Gd (FeGd), Sm (FeSm), Eu (FeEu)] are isostructural. All show layer structures in which the Fe­(notpH)2– unit serves as a metalloligand to link four equivalent LnIII ions into a layer. Compound [CuLa­(notpH2)­(H2O)2]­ClO4·3H2O (CuLa) displays a chain structure, where the Cu­(notpH2)2– unit connects the LaIII ions into a chain. The magnetic properties of FeLn are studied.
