“…However, the center Ln 3+ ion of title complexes is nine‐coordinated, exhibiting a distorted monocapped square antiprismatic coordination geometry. Compared with another reported complexes Er(2,3‐DMOBA) 3 (terpy)(H 2 O) and [Nd(2,3‐DMOBA) 3 (terpy)(H 2 O)] 2, the two complexes are mononuclear and binuclear structures, respectively. They all contain coordination water and no free ethanol molecules.…”

A series of novel trivalent lanthanide complexes, [Ln(2,3-DMOBA)3(5,5′-DM-2,2′-bipy)]2·C2H5OH (Ln = Eu(1), Sm(2), Gd(3), Ho(4) Er(5), Pr(6), Nd (7)) (2,3-DMOBA = 2,3-dimethoxybenzoate, 5,5′-DM-2,2′-bipy = 5,5′-dimethy-2,2′-bipyridine), have been successfully synthesized and structurally validated by single crystal diffraction. All complexes discussed herein feature a binuclear structure, and contain only one free ethanol molecule, which is interesting in the lanthanide complexes. The coordination number of center Ln3+ ions is nine, showing a distorted monocapped square anti-prismatic coordination geometry. Through a pair of alternating identical C-H···O hydrogen bonding interactions between two 2,3-DMOBA ligands on the same lanthanum binuclear unit with 5,5′-DM-2,2′-bipy ligands on two neighboring units, the binuclear complexes can form one-The thermal analysis of these complexes are investigated by TG-DSC/FTIR, the result show that the decomposition process of complexes are mainly divided into four stages with the formation of the respective oxides.The visible light emission experiment of complex 1 is carried out, and the characteristic luminescence behavior of intense red light is exhibited. What'more, fluorescence lifetimes as well as the fluorescent quantum yield of complex 1 is calculated. And the magnetic properties of complexes 3-5 are also studied.

“…[2] This problem has reduced the effectiveness of drugs and imposed huge costs on the health system of countries. [3][4] In addition to drugs, various materials have been used as antibacterial agents, including metal oxides, [5] metal complexes, [6][7][8][9] and organic-inorganic hybrid materials. [10][11] Coordination polymers (CPs) are a kind of organic-inorganic hybrid materials, and there is considerable interest in the design and synthesis of them in the fields of supramolecular chemistry and crystal engineering.…”

Dinuclear 1D coordination polymer of [NaCu2(pdc)2(H2O)4(OH)]n (1) (H2pdc = Pyridine‐2,6‐dicarboxylic acid) was synthesized by the solvothermal method, and its structure was investigated by single‐crystal X‐ray diffraction analysis. 1 has zigzag chains, which are converted to a 3D network through hydrogen bond interactions. Also, 1 was synthesized by sonochemical method (1‐Sono). The structures of 1 and 1‐Sono were characterized by FT‐IR, XRD, FE‐SEM and thermogravimetric (TG) techniques. Antibacterial activity was evaluated by agar well diffusion method. Release of copper ions, chelation, and stability were the factors influencing antibacterial property. More effect of compounds against S. aureus strain was observed, and 1‐Sono exhibited better antibacterial activity than 1.
