Two new manganese(III) Schiff base complexes MnL2N3 (1) and MnL2NCS (2) where HL is 4-bromo-2-[(Z)-{[2-(thiophene-2-yl)ethyl]imino}methyl]phenol) were synthesized and characterized by UV–Vis. absorption spectra, FT-IR, TGA Analyses, and single-crystal X-ray diffraction technique. Structural studies reveal that the metal sites in complexes 1–2 are six-coordinated by two phenoxy oxygen atoms, two imine nitrogen atoms of two moles of Schiff base ligand, HL, and two nitrogen atoms from the azide or one nitrogen atom and one sulphur atom from thiocyanate ligands, respectively. The geometry around the metal center is twisted octahedral geometry with a MnN4O2 (for 1) and MnN3O2S (for 2) chromophore. Hirshfeld surfaces associated with 2D fingerprint plots have been used to analyze intermolecular interactions in crystal packing. Crystal packing of both complexes shows the interchain π⋯π stacking interactions between one-dimensional polymeric chains. [ABSTRACT FROM AUTHOR] |
