[Zn2Ac2(μ-Ac)2(bpymb)]n (Ac, acetate; bpymb, 1,4-bis(4-pyridylmethyl)benzene), a 2D coordination polymer obtained with a flexible N,N’-ditopic bipyridine linker
The combination of the flexible N,N’-ditopic ligand 1,4-bis(4-pyridylmethyl)benzene (bpymb) with zinc(II) acetate (ZnAc) affords the synthesis of the two-dimensional coordination polymer [Zn2Ac2(μ-Ac)2(bpymb)]n, which was structurally characterized by single crystal XRD. In the resolved structure, t...

| Resumo: | The combination of the flexible N,N’-ditopic ligand 1,4-bis(4-pyridylmethyl)benzene (bpymb) with zinc(II) acetate (ZnAc) affords the synthesis of the two-dimensional coordination polymer [Zn2Ac2(μ-Ac)2(bpymb)]n, which was structurally characterized by single crystal XRD. In the resolved structure, the molar ratio metal:ligand was 2:1 for Ac:Zn. However, half of the acetate units are acting as bridging ligands, which allows the building of a layered structure. The description of this new structure increases the numerous family of compounds involving zinc acetate and a ditopic N,N’- ligand, and demonstrates a new possible architecture. The obtained coordination polymer was also characterized by elemental analysis, ATR-FTIR spectroscopy and TGA analysis. Besides, the photoluminescence properties of this compound where measured, showing that the weak photoluminescence of the free bpymb ligand increases after polymer formation. |
