Crystal structure of a new manganese(III) complex with tetradentate Schiff base N,N′-O-phenylenebis(4-methoxysalicylideneimine)

A new manganese(III) complex [Mn(L)(NCS)] ( 1 ) is synthesized from the Schiff base ligand N,N′- O -phenylenebis(4-methoxysalicylideneimine) (H 2 L: derived from the condensation of 4-methoxy salicylaldehyde with O -phenylene-diamine) with Mn(NO 3 ) 2 ∙4H 2 O and KSCN in a methanol/water solvent mixture. This complex is characterized by elemental analysis, FT-IR and single crystal X-ray diffraction. It crystallizes in a monoclinic system, with space group P 2 1 / c and four molecules in the unit cell ( Z = 4). The crystal structure shows [Mn(L)(NCS)] units joined together by the Mn∙∙∙S secondary bonding interaction (SBI) to form infinite zigzag chain structures.
