Abstract

A novel dichlorodi(E)-N′-(4-methoxybenzylidene)benzohydrazide manganese(II) (ENMB-Mn) complex has been successfully synthesized using (E)-N′-(4-methoxybenzylidene)benzohydrazide (ENMB) as ligand. The structure of the ENMB-Mn complex was studied by single crystal X-ray diffraction, UV-Visible, FTIR, thermogravimetric analysis (TGA) and Hirshfeld surface analysis. Results of single crystal X-ray diffraction found that the structure of ENMB-Mn complex crystal is triclinic with space group P-1 and lattice parameters of unit cell a, b and c values were 7.1900 Å, 8.9094 Å and 11.8130 Å, respectively. The structure of ENMB-Mn complex clearly indicates complete octahedral geometry [Mn(ENMB)2Cl2] with manganese(II) ion, where the ENMB and chlorine atoms ratio is 1:2:2, respectively. Further, the molecular properties like Hirshfeld surface analysis mapping are reported.
