The [MnL1]+ (a) and [MnL2]+ (b) complex cations were prepared by complexation of Mn(III) to the Schiff base chelates formed from condensation of 3-nitrosalicylaldehyde or 5-nitrosalicylaldehyde, respectively, with 1,2-bis(3-aminopropylamino)ethane and were crystallized with NO−3, (1a/b), ClO−4, (2a/b), PF−6, (3a/b), CF3SO−3 (4a/b), and BPh−4 (5a/b) counterions. Magnetostructural analysis reveals a minor trend in the spin state preference depending on the position of the nitro substituent where the orientation is dependent on crystal packing.
