ABSTRACT:

The coordination mode of the title ligand, 1 ( synthesised for the first time and abbreviated as EMPyPzC and characterised by elemental analyses, mass, IR and 1H-NMR spectral parameters), is investigated by way of isolation of its solid complexes of CoII, NiII and CuII with various counter ions, X (X = Cl, Br, NO3, SCN, BF4, ClO4,
