“…Compared with the emission bands of 1 and free H 4 L ligand, we notice that compound 1 has an obvious red-shift of 75 nm. According to previously reported literatures, the luminescent emission of compound 1 may originate from the ligand-to-metal charge transfer (LMCT) [25,26].…”

Presented here is a new Cd(II) coordination polymer, namely [Cd 3 (L) 2 (H 2 O) 2 ] n Án(H 2 bpp) (1 H 4 L = 6-(3 0 ,4 0 -dicarboxyl-phenoxy) isophthalic acid, bpp = 1,3-di(4-pyridyl)propane), which was synthesized by the solvothermal reactions of Cd(NO 3 ) 2 Á4H 2 O, H 4 L and bpp. Single crystal X-ray diffraction analysis reveals that compound 1 features a 3D anionic framework with the protonated H 2 bpp cations as the organic templates. Moreover, the luminescent and photocatalytic properties of compound 1 were investigated in detail.

“…Notably, the luminescence intensity of complexes 1-3 is stronger than that of AMPPA ligand. It is probably due to the coordination of those ligands to Cd(II) center, which effectively increases the ligands' rigidity and asymmetry so that reduce the non-radiative decay of the intraligand (p-p*) excited state [68].…”

Three new N-(5-amino-2-methylphenyl)-4-(3-pyridyl)-2-pyrimidineamine Cd(II) coordination polymers, namely, {[Cd(AMPPA) 2 (H 2 O) 2 ]Á(NO 3 ) 2 ÁH 2 O} n (1), {[Cd (AMPPA) 2 (ipa)]Á2H 2 O} n (2) and {[Cd(AMPPA) 2 (Hbtc)]Á 2H 2 O} n (3) (AMPPA = N-(5-amino-2-methylphenyl)-4-(3-pyridyl)-2-pyrimidineamine, H 2 ipa = isophthalic acid and H 3 btc = 1,3,5-benzenetricarboxylic acid) have been synthesized under hydrothermal conditions. X-ray diffraction analysis reveals that complex 1 exhibits one dimension (1D) coordination polymers when only the AMPPA ligand was employed. With the introduction of the building blocks (H 2 ipa and H 3 btc) into the reaction system of 1, complexes 2 with 2D layer and 3 with 3D networks were isolated, respectively. The effect of the building blocks in the construction of complexes 1-3 has been discussed. In addition, all complexes display strong luminescence in the solid state. Graphical Abstract Three N-(5-Amino-2-methylphenyl)-4-(3-pyridyl)-2-pyrimidineamine cadmium coordination polymers have been designed and isolated by the introduction of the building blocks of H 2 ipa and H 3 btc featuring 1D chain, 2D layer and 3D network with strong luminescence in the solid state.

“…However, the complex shows blue-shift with respect to the free corresponding ligands. It may derive from the coordination effects of bpy and/or carboxylic acid to Zn(II) ions, which increases the ligand conformational rigidity and asymmetry of the ligands, thereby reducing the non-radiative decay of the intraligand excited state [45][46][47].…”

Unusual Very Strong O–H···O Hydrogen Bonding in Zinc Complex: Crystal Structure and Photoluminescence of [Zn(HL)(bpy)2(H2O)]2(L) (L = O2C(CF2)6CO2, bpy = 2,2′bipyridine)

The centrosymmetric dimer zinc compound, [Zn(HL)(bpy) 2 (H 2 O)] 2 (L), (L = O 2 C(CF 2 ) 6 CO 2 , bpy = 2,2 0 -bipyridine), was obtained through the reaction of Zn(ClO 4 ) 2 Á6H 2 O, bpy and perfluorosuberic acid. Zn(II) centre is coordinated by four N atoms from two bpy ligands and two O atoms from a water molecule and monoanionic suberate ligand in a distorted octahedral coordination environment. The unit structure contains crystallographically centrosymmetric suberate anion which acts as a bidentate bridging ligand between each cationic monomer complex unit via hydrogen bonding. The very strong interaction of hydrogen bonding of hydoxycarbonyl-carboxylate system in solid state has O-HÁÁÁO 2.436(3) Å (OÁÁÁH = 1.25(6) Å and HÁÁÁO = 1.19(6) Å ). These units are also connected to each other via pÁÁÁp, C-HÁÁÁp, C-FÁÁÁp and FÁÁÁF stacking interactions, C-HÁÁÁO, O-HÁÁÁO and C-HÁÁÁF hydrogen bonds giving rise to a multi-dimensional network. The complex is the first reported example of a coordination compound based on both bpy ligands together with perfluorosuberic acid. Moreover, compound exhibit intense solid state fluorescent emissions at room temperature.
