Zn^II/Ni^IIcoordination polymers with 2-phenylsuccinate and 1,3-bis(4-pyridyl)propane

A series of coordination polymers constructed by 2-phenylsuccinic acid and flexible bis(imidazole) ligands: Syntheses, structures, and photoluminescent properties

“…The Zn1 atom is four-coordinated and forms a disordered tetrahedral geometry, which is completed by two carboxylate oxygen atoms from two distinct phsuc moieties and two nitrogen donors from two pbix ligands. The lengths of the Zn-O (1.951(6)-1.959(6) Å) and Zn-N (2.002(7) and 2.000(7) Å) bonds are comparable to those observed in the related literature [35]. The adjacent Zn(II) ions are connected by bridging carboxylate groups of phsuc ligands into a 1D double chain with the Zn⋅⋅⋅Zn distance of 9.291 Å.…”

“…3a, the Zn1 ion is four-coordinated by two carboxylate oxygen atoms from two phsuc ligands and two nitrogen atoms from obix ligands, showing a distorted tetrahedral structure. The Zn-O and Zn-N bond lengths of previously reported Zn(II) complexes based on succinate ligands are similar to those of compound 3 [35]. The phsuc ligand is fully deprotonated and acts as bridging ligands with bis(monodentate) coordination modes to connect the Zn(II) ions to form a 1D linear structure (Fig.…”

Layered exfoliable crystalline materials based on Sm-, Eu- and Eu/Gd-2-phenylsuccinate frameworks. Crystal structure, topology and luminescence properties

“…Even though this ligand has been poorly explored as building block, the tendency mentioned above has been demonstrated in a few examples involving TM ions: five 1D and 2D MOFs based on Cu(II) and different auxiliary molecules 14 , one 1D Zn(II) MOF and one 2D Ni(II) MOF. 15 As far as we know, the interaction between REE ions and H 2 psa for the construction of functional MOFs has not been studied. Regarding the inorganic component, Eu(III) and Tb(III) are the preferred among the whole lanthanide ions for optical devices due to their intense, long-lived, and line-like emission in the visible region.…”
