Design and construction of Zn(II) coordination polymers made by pincer type pyridine-hydrazine based ligands

A new series of five zinc (II) coordination polymers, namely [Zn(L-I)(NO3)(OH2)](n) (1), [Zn(L-I)(CH3COO)](n) (2), [Zn(L-I)(NCS)](n) (3), [Zn(L-II)(CH3COO)](n) (4), and {[Zn-2(L-II)(2)(N-3)(2)] center dot H2O}(n) (5), has been self-assembled from different zinc (II) salts and pyridine-hydrazine ligands {HLI = 2-pyridinecarbaldehyde isonicotinoyl hydrazone, and HLII = 2-acetyl-pyridyl-isonicotinoylhydrazone} and has been structurally characterized. In all compounds, the ligand is singly-deprotonated and coordinates to the zinc center in the enolic form (=N-N=C-O-). In other words, the pyridine-hydrazine ligand acted as a tetradentate negatively charged chelating-bridging ligand and coordinated to the metal centers in N, N, O pincer mode and the Para-nitrogen of the pyridine ring coordinated to the zinc center of the adjacent unit. In compounds (1)-(4) the ancillary ligands act as terminal ligands and the zinc centers bridging by the pyridine-hydrazine building blocks formed one-dimensional 1D coordination polymers, whereas the azide N-3(-) anion in compound (5) further acted as a bridging agent and led to the formation of two-dimensional 2D network. A detailed analysis of Hirshfeld surfaces and fingerprint plots allows a comparison of intermolecular interactions in (1)-(5), which are crucial in building supramolecular architectures.
