“…18,33,34 Previously, we reported synthesis, experimental, and density functional theory (DFT)-computational investigations on the pyridoxal-derived Schiff bases and their complexes. 18,28,[35][36][37][38][39][40][41][42] Some of \them exhibit significant analytical 37,38 and catalytic 28 properties. Also, an Mn(II) complex of the N,N′-dipyridoxyl(1,2-diaminobenzene)…”
