Coordination patterns: Spectroscopic and electrochemical investigation on Mn(II) complexes with macrocyclic ligands derived from two different organic skeletons

Two novel macrocyclic ligands and their complexes Mn(L¹ and L²)]X₂ (L¹ and L² = 1,10-diaza-5,6,15,17-tetraoxa (tetrathia)-2,3:8,9:12,13,18:19-tetrabenzocyclododeca-10,20-diene; X = Cl, NO₃, NCS, SO₄) were primed and their capacity to sustain the Mn²⁺ ion in solid, as well as in aqueous solution, was resoluted from an assortment of physicochemical measurements, viz., elemental analyses, molar conductance measurements, magnetic susceptibility measurements, mass, IR, ¹H NMR electronic, ESR spectral studies, and cyclic voltammetric (CV) measurements.
