Versatile monometallic coordination polymers constructed from 4,4′-thiobis(methylene)bibenzoic acid and 1,10-phenanthroline. Synthesis, structure, magnetic and luminescence properties

Four novel mononuclear coordination polymers [Co(tmba)(phen)(H2O)(0.)(5)](n), (1), [Mn(tmba)(phen)](n) (2), [Zn(tmba)(phen)](n) (3) and [Cd(tmba)(phen)(H2O)](n) (4), H(2)tmba = 4,4'-thiobis(methylene)bibenzoic acid, phen = 1,10-phenanthroline, were synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction, powder X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis. Single crystal X-ray diffraction showed that compounds 1, 3 and 4 build 1D chains whereas complex 2 displays a 2D layer configuration. Magnetic susceptibility measurements indicate that compound 1 exhibits the coexistence of spin-orbit coupling and antiferromagnetic interaction in the binuclear Co(II) center. Compound 2 manifests an antiferromagnetic interaction within the Mn(II)-carboxyl chain. Moreover, based on the solid state emission spectra of compounds 3 and 4, and of H(2)tmba and phen, relevant fluorescence properties have been investigated.
