Designs, Syntheses, Structures And Properties Of Ligands, Coordination Polymers And Complexes Of Isonicotinoyl Hydrazones

Two ligands, two coordination polymers and four complexes were synthesized:(1) Schiff base ligand of N-isonicotinamidodiacetyl(L1) and its two coordination polymers [Zn₂L₂¹]n(NO₃)_2n·2nH₂O and [Zn₂L₂¹]n(ClO₄)_2n·2nH₂O.(2) Four N-isonicotinamidosalicylaidimine complexes: [CuL₂Cl]·H₂O, [FeL₂Cl₂] and two chromium (III) complexes with N-isonicotinamidosalicylaidimine. (3) Schiff base ligand of N-isonicotinamidoisotin(L3).Apart from the two chromium(III) complexes with the N-isonicotina- midosalicylaidimine ligand, the X-ray single crystal structure determinations of which are in processing, the structures of the two ligands, the two coordination polymers and the other two complexes were characterized both by spectral methods and X-ray single crystal diffraction. The weak interactions in the crystals are discussed. There are large channels in the crystal structures of the two coordination polymers [Zn₂L₂¹]n(NO₃)_2n·2nH₂O and [Zn₂L₂¹]_n (ClO₄)_2n·2nH₂O.
