Synthesis and characterisation of one trinuclear copper complex, ([Cu3L3O]ClO4) (1) and one nickel complex ([Ni(L'H)2(dmso)2](ClO4)2) (2) with Schiff base ligands: (3Z)-3-((Z)-(1-(thiophen-2-yl)ethylidene)hydrazono)butan-2-one oxime (LH) and 1-(pyridin-2-yl)ethylidene)hydrazono)butan-2-one oxime (L'H). 1 shows high catecholase activity and has also been tested as a catalyst for the synthesis of benzylimine. 2 shows phenoxazinone synthase activity.
