A new manganese(III) complex [Mn(L)(NCS)] (1) is synthesized from the Schiff base ligand N,N¢- O -phenylenebis(4-methoxysalicylideneimine) (H2L: derived from the condensation of 4-methoxy salicylaldehyde with O -phenylene-diamine) with Mn(NO3)2×4H2O 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 21/ 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.
