Self-assembly of 2-hydroxyl-5-carboxylbenzenesulfonic acid (H3L) and rare earth (RE) metal nitrates together with 1,10-phenanthroline (1,10-phen) generates sixteen complexes, namely, [RE(NO3)(H2O)8]·2(H2L)·2H2O (1-RE) (RE = Nd, Sm, Gd, Tb, Dy), [RE(NO3)2(H2O)6]·[RE(H2O)9]·4(H2L)·4H2O (2-RE) (RE = Ho and Y), [La(L)(H2O)3]n·3nH2O (3-La), [Eu2(L)2(1,10-phen)2(H2O)2]n·nH2O (4-Eu), [Tb2(L)2(1,10-phen)3(H2O)2]n·nH2O
2-羟基-5-羧基苯磺酸(H 3 L)和稀土(RE)金属硝酸盐与1,10-菲咯啉(1,10-phen)的自组装产生了十六种络合物,即[RE(NO 3)(H 2 O)8 ]·2(H 2 L)·2H 2 O(1-RE)(RE = Nd,Sm,Gd,Tb,Dy),[RE(NO 3)2(H 2 O)6 ]·[RE(H 2 O)9 ]·4(H 2 L)·4H 2 O(2-RE)(RE = Ho和Y),[La(L)(H 2 O)3 ] n · 3nH2 O(3-La),[Eu 2(L)2(1,10-phen)2(H 2 O)2 ] n ·nH 2 O(4-Eu),[Tb 2(L)2(1 ,10-phen)3(H 2 O)2 ] n ·nH 2 O(5-Tb),[RE(L)(1,10-phen)2 ] n ·nH 2 O(6-RE)(RE = Dy,Ho和Y)和[RE(L)(1,10-phen)(H 2
