Syntheses, crystal structures and magnetic properties of there low-dimensional CPs based on V-shaped diacylhydrazidate ligand from in situ acylation reaction
Through employing the in situ acylation of N2H4 with ODPA (ODPA=4,4′-oxydiphthalic dianhydride), three diacylhydrazidate-extended coordination polymers, M(ODPTH)(H2O)3 (M=Fe (1), Co (2), Ni (3); ODPTH=4,4′-oxydiphthalhydrazidate), were obtained under solvothermal conditions. The X-ray single-crystal diffraction analysis reveals that compounds 1, 2 and 3 are isomorphous and feature 1D double chain structures that are further connected through O–H⋯O hydrogen bonds into 3D supramolecular networks, which are stabilized by two kinds of offset face-to-face π⋯π interactions. All of title compounds were characterized by IR spectroscopy, elemental analysis, X-ray power diffraction and TG analysis. Furthermore, variable-temperature magnetic susceptibilities of compounds 1, 2 and 3 indicate that there exist antiferromagnetic interactions between Fe(II), Co(II) and Ni(II) ions, respectively.
