Abstract

The mixed-ligand coordination polymers containing 2,2'-dimethylglutarate (dmg) and 1,2-bis(4-pyridyl) ethane (dpetan) ligands, [Co(mu(3)-dmg)(mu-dpetan)](n) (1), [Ni-2(mu-dmg)(2) (H2O)(2) (mu-dpetan)(2)](7), (2) and [Zn(mu-dmg)(H2O)(mu-dpetan)(0.5)](n) (3), were synthesized through a hydrothermal method and characterized by single-crystal X-ray diffraction. Complexes 1 and 2 are a two-dimensional (2D) structures, in which Co (II) or Ni(II) ions were bridged by dmg and dpetan ligands. Complex 3 exhibits a one-dimensional (1D) ladder-like structure, which is further extended in 2D through hydrogen bonding interactions. dmg ligand exhibits three different coordination modes in 1-3 and the coordination mode in the complex 2 has been unprecedented up to now. The thermal properties of the complexes were investigated. Moreover, photoluminescence property of complex 3 was recorded in the solid state at the room temperature. (C) 2018 Elsevier Ltd.
