“…The reason is not only their abundant and various intriguing structures, but also their possible applications such as magnetic materials [9][10][11], fluorescent materials [12][13][14][15] and biological field [16][17][18][19]. Since aromatic carboxylic acid ligands can sensitize light of lanthanide cations, they are often used in the aspect of constructing innovative complexes.…”

The crystal structures of complexes [Tb (3-Br-4-MBA) 3 phen] 2 (1), [Ho(3-Br-4-MBA) 3 (phen)H 2 O] 2 (2) and [Er(3-Br-4-MBA) 3 (phen)H 2 O] 2 (3) (3-Br-4-MBA=3-bromine-4-methylbenzoate, phen=1,10-phenanthroline) have been solved by single-crystal X-ray diffraction methods. All obtained products were examined and characterized by elemental analysis, molar conductivity, IR, UV and XRD techniques. The thermogravimetric analysis of 1 to 3 was studied, indicating that the decomposition processes of 2 and 3 are different from 1. The mass loss of the first step for 2 and 3 is attributed to the H 2 O molecules. The three-dimensional IR accumulation spectra of gaseous of 1 to 3 were also recorded. Complex 1 emits strong and bright green fluorescence under UV light at the room temperature. The bacteriostatic activities of the three complexes against bacteria, such as Escherichia coli and Staphylococcus aureus, and fungus (Candida albicans) were tested.

“…Because CuL and benzotriazole‐5‐carboxylate both contain O‐donors, which prefer to bond to Ln III ions. Especially, benzotriazole‐5‐carboxylate has five coordination atoms and different bonding modes, which makes it easy to design and construct extended frameworks . In our previous work, although some 3d‐3d′ heterometallic coordination polymers based on macrocyclic oxamide and aromatic multicarboxylate have been obtained, those containing 3d‐4f have been prepared rarely.…”

Two heterometallic 3d-4f coordination polymers, [Gd(CuL) 2 (Hbtca)(btca)(H 2 O)]·2H 2 O (1) and [Er(CuL) 2 (Hbtca)(btca) (H 2 O)]·H 2 O·CH 3 OH (2) (CuL, H 2 L = 2 ,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-dien; H 2 btca = benzotriazole-5carboxylic acid) were synthesized by solvothermal methods and characterized by single-crystal X-ray diffraction. Complexes 1 and 2 exhibit a double-strand meso-helical chain structures formed by [Ln III Cu II 2 ] * Dr. Y.-Q. Sun 1460(Ln III = Gd, Er) units by oxamide and benzotriazole-5-carboxylate bridges. They are isomorphic except that one free water molecule of 1 is replaced by a methanol molecule. All 1D chains are further interlinked by hydrogen bonds resulting in a 3D supramolecular architecture. The magnetic properties of the compound 1 and 2 are also discussed.cyclic oxamide and aromatic multicarboxylate have been obtained, [33][34][35][36][37][38] those containing 3d-4f have been prepared rarely.

New 1D polymers, with the general formula [Ln(4phbz) 3 ] n , where Ln = Sm, Eu, Gd, Tb, Dy, Ho, and 4-phbz is the 4-phenylbenzoate anion, were synthesized by the reaction of Ln(NO 3 ) 3 ·xH 2 O, 4-phenylbenzoic acid, and dry KOH. Thermal analysis shows that [Eu(4-phbz) 3 ] n is thermally stable under an inert gas up to 350°C, and it melts at 297°C. It is shown that the 4-phenylbenzoate anion [E(T 1 ) ≈ 22500 cm -1 ] in [Ln(4-[a] N.Figure 7. Top: Excitation (λ em = 17391 cm -1 ).
