Synthesis, crystal structure, Hirshfeld surface analyses, antimicrobial activity, and thermal behavior of some novel nanostructure hexa-coordinated Cd(II) complexes: Precursors for CdO nanostructure

Abstract

A new tetradentate Schiff base ligand entitled as (L = (N2E, N2′E)-N1, N1′-(ethane-1,2-diyl)bis(N2-((E)-3-(2-nitrophenyl)allylidene)ethane-1,2-diamine) and its six cadmium(II) complexes formulated as CdLX2 in which X is Cl, Br, I, NO3, NCS, or N3 were synthesized under ultrasound irradiation and characterized by various physical and spectral techniques. Moreover, some complexes were also prepared in nanostructured dimensions confirmed by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA), and X-ray powder diffraction (XRPD) techniques and then were used as precursor for preparation of CdO nanoparticles via direct calcination at 600°C. As typical, the crystal structur..
