5-Sulfosalicylato Cu(II), Zn(II) and Ni(II) coordination compounds with benzohydrazide: Synthesis, structure and luminescent properties

Three new 5-sulfosalicylato 3 d-metal coordination compounds [Cu-II(Bhz)(2)(H(2)SSal)(2)] ( 1 ), [Zn(Bhz)(2) (H(2)SSal)(2)] ( 2 ) and [Ni-II(Bhz)(3)]3(HSSal)(3) .7.5H(2)O.0.5(C2H5OH) ( 3 ) (where Bhz - benzohydrazide, H2SSal- and HSSal(2)- - 5-sulfosalicylate anions) have been synthesized and studied by elemental analysis, IR spec-troscopy and single-crystal X-ray diffraction. Luminescent spectra for 1 -3 were measured at room temper-ature. The results obtained show the nature of the metal ions as the deciding factor in the organization of the coordination compounds as well in their photoluminescence properties. The synthesized coordination compounds can be potential luminescent materials. (C) 2022 Elsevier B.V. All rights reserved.
