Present work reviews the synthesis of Schiff base ligand derived from N-(1-Naphthyl) ethylenediamine with 1,2diphenylethane-1,2-dione in the ratio of 1:2 and its metal complexes. The colored complexes prepared were of type [M 2+ L]X2, where M 2+ = Cu, Co, Zn, L= Synthesised schiff base ligand and X= Cl. The chelation of the ligand to metal ions occurs through the four nitrogen atoms of the liga...

we give the concept of ‘braiding’ for 2-groupoids, and we show that this structure is equivalent tobraided regular, crossed modules.
