Abstract

N,N'-((Hydrazine-1,2-diylidene-bis(methanylylidene))bis(2,1-phenylene))bis(4-methylbenzene-sulfonamide) (H2L) and its binuclear complexes Zn2L2 and Co2L2 are synthesized. The compositions and structures of H2L and its complexes are determined by elemental analysis and IR and 1H NMR spectroscopy (for Zn2L2). The structures of H2L and Co2L2 are determined by XRD (CIF files CCDC no. 2405868 for H2L and no. 2390599 for Co2L2·4DMSO). The magnetic properties of Co2L2 and photoluminescence properties of H2L and Zn2L2 are studied. The Zn(II) complex exhibits the photoluminescence properties in an acetonitrile solution and in the solid state ( \(\lambda _{{{\text{max}}}}^{{{\text{fl}}}}\) = 584 and 532 nm) with quantum yields of 0.06 and 0.68, respectively. The Co(II) complex exhibits the properties of slow magnetic relaxation.
