Three new Zn(II) coordination polymers, {[Zn(L1)2(H2O)2]·4H2O}n (1), {[Zn(L2)(H2O)2]·0.5H2O}n (2), and {[Zn1.5(L1)(o-bdc)(H2O)]·0.5H2O}n (3) (HL1 = 3,5-di(1,2,4-triazol-1-yl)benzoic acid, H2L2 = 5-(triazol-1-yl)isophthalic acid, o-H2bdc = 1,2-benzenedicarboxylic acid), were successfully synthesized and characterized. Compound 1 exhibits 1D chain structure containing [Zn(L1)2] unit. Compound 2 shows a 2D plane with the ratio of Zn:L2 was 1:1 since L2 can match the positive charge of Zn(II). When L1 and o-bdc2– were presented together, Zn(II) centers are linked by L1 to form 2D double layers, then o-bdc2– further connected the adjacent layers to generate final 3D framework of 3. The ligand charges may play key roles in tuning the frameworks of compounds 1–3. The solid state luminescence of compounds 1–3 and all ligands have been investigated here.

Using a hydrothermal synthesis, the self-assembly of MnII ions and 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene with two dicarboxylate ligands, 2-nitrobenzene-1,4-dicarboxylic acid (2-H2ata) and 5-methylbenzene-1,3-dicarboxylic acid (5-CH3-H2ip) constructed two interesting coordination polymers: [Mn(2-ata)(bimb)]n (1) and {[Mn(5-CH3-ip)(bimb)1.5]·2H2O}n (2), where bimb refers to 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene. Their structures were determined by single-crystal X-ray diffraction, elemental analysis, and infrared spectroscopy. Complex 1 exhibits a 2-fold interpenetrated pcu net. Complex 2 shows an unusual polycatenated 2D+2D→3D framework. In addition, the solid-state photoluminescent properties of 1 and 2 were investigated at room temperature.

AbstractThe last few years have seen an increasing interest in the study of lanthanide-silver (Ln-Ag) heterometallic coordination polymers due to their potential applications. It has led to intense activity of chemists to produce Ln-Ag heterometallic coordination polymers and investigate their properties. In this review, we summarize recent research development in the fascinating and challenging field of Ln-Ag heterometallic coordination polymers. This review covers 182 Ln-Ag heterometallic coordination polymers, which are categorized by the kind of ligand as N-heterocyclic carboxylate ligands and others. There are three categories of Ln-Ag coordination polymer based on N-heterocyclic carboxylate ligands: one dimensional (1D), 2D, and 3D. The 3D part was divided into Ln-Ag coordination polymers based on pyridine carboxylate ligands and other N-heterocyclic carboxylate ligands. This perspective illustrates the coordination features of compounds constructed by N-heterocyclic carboxylate ligands. Luminescent properties are also discussed.
