Cobalt(II) perchlorate reacts with tridentate chelating Schiff base, N-((phenyl)formylidene)-N'-(2-aminoethyl)ethane-1,2-diamine (pfad) and azide in methanol-acetonitrile solution in 1: 1: 3 molar ratio to afford a chiral cobalt(III) complex [Co(pfad)(X)(3)] (1). The meridional arrangements of three N atoms of the tridentate chelator and three N-3(-) in cobalt(III) center that construct a 3D supra-molecular network through N-H...N hydrogen bonding and weak pi...pi interaction. Single band at 435 nm is observed in the solid-state emission spectrum.
