Heterometallic One-Dimensional Tetranuclear Cu-Na Cluster-Based Polymers: Room Temperature Synthesis, Structures, and Properties

Two novel heterometallic one-dimensional tetranuclear Cu-Na cluster-based polymers Complexes, [Cu2Na2(L-1)(2)(AcO)(2)(EtOH)(2)](n) (1, H2L1 = 2-methoxy-6-[(1H-tetrazol-5-ylimino)-methyl]-phenol) and [Cu2Na2(L-2)(2)(AcO)(2)(H2O)(CH3OH)(2)](n) (2, H2L2 = 2-ethoxy-6-[(1H-tetrazol-5-ylimino)-methyl]-phenol) are central symmetry copper- sodium structures which were synthesized by reacting copper acetate monohydrate and sodium hydroxide with 2-hydroxy-benzaldehyde ramification Schiff base in a micro vial at room temperature. Both the polymer complexes were characterized by elemental analysis, infrared spectroscopy, and X-ray single-crystal diffraction analysis. Moreover, the luminescent properties of 1 and 2 were also studied, and intermolecular interaction was analysized using Hirshfeld surface analysis. The coordination mode of the bridged ligand L in 1 and 2 is mu(5)-L-kappa O-7(1), O-2:O-2, N-1, N-2, N-3, N-4.
