The unsymmetrical bis-Schiff base manganese complexes with either benzo-10-aza-crown ether pendants ( MnL1Cl, MnL2Cl) or morpholino pendant (MnL3Cl,MnL4Cl) have been employed as models for hydrolase by studying the hydrolysis reactions of p-nitrophenyl picolinate (PNPP). The effects of complex structures, reaction pH and reaction temperature on the rate of PNPP hydrolysis have been investigted. All four complexes exhibit high catalytic activity and the rate increases with pH increasing at 25 oC. The complexes of ligands containing a crown ether group exhibit higher catalytic activities than the non-crown analogues.

A pentadentate Schiff-base ligand 3,5Cl-L2− and NCSe− form a iron(iii) mononuclear complex [Fe(3,5Cl-L)(NCSe)], which shows a thermally induced spin crossover with a broad hysteresis width of 24 K between 123 K (warming) and 99 K (cooling).
