Abstract
New complexes of the general compositions M(LH2)2X2 (M = Co, Ni, Cu, Zn; X = Cl, NCS, NO3), M(LH2)2Cl2. EtOH (M = Ni, Cu; EtOH = ethanol), M(LH)2.nH2O (M = Co, Ni, Cu, Zn, Pt; n = 1, 2, 3), Pd(LH)Cl·H2O, CuL·3H2O and Zn(LH) (OH) ·2H2O, where LH2 = N-(3-carboxylphenyl)pyridine-2′-carboxamide, have been isolated. The complexes were characterised by elemental analyses, conductivity measurements, TG patterns, magnetic susceptibilities and spectral (1H-NMR, IR, electronic) studies. Distorted octahedral and square planar stereochemistries are assigned in the solid state. Coordination of the neutral carboxylic group is not observed for the complexes of LH2; the carboxylate ion exhibits monodentate coordination in the compounds of LH− and L2-. The neutral amide group of LH2 and LH− is coordinated to Co(II), Ni(II), Cu(II) and Zn(II) through oxygen, while nitrogen and oxygen amide coordination is observed for CuL·3H2O. The secondary amide bond shows the rare iminol type of coordination in Pd(LH)Cl·H2O.Keywords
