Reactions of the tridentate Schiff-base ligands HL1, HL2and HL3formed from pyridine-2-aldehyde and 2-aminophenol plus two of its methoxycarbonyl derivatives, with AgNO3, [Cu(CH3CN)4]PF6, Cu(NO3)2, Co(NO3)2and Zn(NO3)2give complexes of the following types: [Ag(HL)2]NO3; (1a, 2a, 3a); [CuII(HL)L]PF6(1b, 2b, 3b); [CuII(HL)L]NO3(1c, 2c, 3c); and [M(HL)L]2[M(NO3)4] where MCo(II) (1d, 2d, 3d); or Zn(II) (1e, 2e, 3e), which in principle define the basic characteristics of the metal sites in certain metallogrids. The complexes have been characterized by spectroscopic techniques and elemental analysis. The solid state structures of complexes 2b and 2e have been established by X-ray crystallography.
