Hydrothermal reactions of lanthanide(III) chlorides with 4-HOOC−C6H4−CH2NHCH2PO3H2 (H3L) at different ligand-to-metal (L/M) ratios afforded nine new lanthanide(III) carboxylate-phosphonates with two types of 3D network structures, namely, LnCl(HL)(H2O)2 (Ln = Sm, 1; Eu, 2; Gd, 3; Tb, 4; Dy, 5; Er, 6) and [Ln2(HL)(H2L)(L)(H2O)2]·4H2O (Ln = Nd, 7; Sm, 8; Eu, 9). Compounds 1−6 are isostructural and feature
氯化镧系元素(III)与4-HOOC-C 6 H 4 -CH 2 NHCH 2 PO 3 H 2(H 3 L)在不同配体与金属(L / M)比率下的水热反应提供了九种新的镧系元素(III) )具有两种3D网络结构的羧酸酯-膦酸酯,即LnCl(HL)(H 2 O)2(Ln = Sm,1 ; Eu,2 ; Gd,3 ; Tb,4 ; Dy,5 ; Er,6)和[Ln 2(HL)(H 2 L)(L)(H 2 O)2 ]·4H 2O(Ln = Nd,7 ; Sm,8 ; Eu,9)。化合物1 - 6是同构的,并设有一个三维网络,其中LNO 7氯多面体通过桥接CPO互连3四面体为2D无机层平行于BC平面。这些层通过羧酸酯基团的配位基团的配位通过羧酸酯基-膦酸酯基团的有机基团进一步交联。化合物7 - 9也是同构的,并具有由1D镧系元素(III)膦酸酯无机平板组成的3D开放框架,其通过羧酸酯基团的配
