“…[32,[49][50][51][52] The similarity of [Ln 2 (OXA) 3 (H 2 O) 6 ]·4(H 2 O) diffractograms and the standard crystal structure data (CCDC: 816524) confirms a nine-coordinated site with a tricapped trigonal prism geometry [32] ( Figure S4). The diffractograms of the complexes with L = MAL, ADP, SUB, and SEB are comparable to their respective standard crystal structure data, CCDC: 181893, [50] 721892, [49] 700675, [51] and 745638, [52] respectively. These results indicate a mixed bridge-chelate Ln 3 + À L coordination mode as discussed in the FTIR data, even for the MAL ligand that forms chelate rings with 4 and 6 members.…”

The odd–even effect in luminescent [Eu2(L)3(H2O)x]⋅y(H2O) complexes with aliphatic dicarboxylate ligands (L: OXA, MAL, SUC, GLU, ADP, PIM, SUB, AZL, SEB, UND, and DOD, where x=2–6 and y=0–4), prepared by the precipitation method, was observed for the first time in lanthanide compounds. The final dehydration temperatures of the Eu3+ complexes show a zigzag pattern as a function of the carbon chain length of the dicarboxylate ligands, leading to the so‐called odd‐even effect. The FTIR data confirm the ligand–metal coordination via the mixed mode of bridge–chelate coordination, except for the Eu3+‐oxalate complex. XRD results indicate that the highly crystalline materials belong to the monoclinic system. The odd–even effect on the 4 f–4 f luminescence intensity parameters (Ω2 and Ω4) is explained by using an extension of the dynamic coupling mechanism, herein named the ghost‐atom model. In this method, the long‐range polarizabilities (α* ) were simulated by a ghost atom located at the middle of each ligand chain. The values of α* were estimated using the localized molecular orbital approach. The emission intrinsic quantum yield (QnormalLnormalnnormalLnormaln ) of the Eu3+ complexes also presented an the odd‐even effect, successfully explained in terms of the zigzag behavior shown by the Ω2 and Ω4 intensity parameters. Luminescence quenching due to water molecules in the first coordination sphere is also discussed and rationalized.

“…Thus pyridine carboxylic acid as a potential linker has drawn extensive attention in the construction of MOFs [13][14][15][16][17]. And the long chain dicarboxylate [O 2 C(CH 2 ) n CO 2 ] has also a large variation in coordination behavior including chelating, bidentate-bridging or chelating-bridging modes, which allows for the formation of clusters, cage structures or open frameworks [18][19][20][21]. As we know, lanthanide ions, with their high and variable coordination numbers and flexible coordination environments, are good candidates used to provide unique opportunities for constructing unusual MOFs [22][23][24][25][26].…”

Two new lanthanide coordination polymers, [Sm 2 (nic) 3 (ad) 0.5 (H 2 O)(l 3 -O) 2 ] (1), [Pr(nic)(ad)]Á2H 2 O (2) (nic = nicotinic acid, ad = adipic acid) have been synthesized hydrothermally from the self-assembly of the lanthanide ions (Ln 3? ) with rigid nicotinic acid and the flexible adipic acid. They were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Structural analyses reveal that both of the complexes crystallize in triclinic, space group P-1 and have different framework characterization. Because of different coordination modes of nicotinate, complexes 1 and 2 exhibit 2D and 3D framework structure, respectively. In 1, the Sm1 and Sm2 atoms and their corresponding centrosymmetric atoms are connected by bridging oxygen atoms to form a 1D Sm 2 (l 3 -O) 2 polymeric chain along [010] direction. The photoluminescent properties of 1 and thermogravimetric analysis of 1 and 2 are discussed in detail.
