abstract	The new Pd(II), Pt(II), Re(V), Mo(VI) and W(VI) complexes of 2-hydroxynicotinic acid (H(2)nicO), trans-[PdCl(HnicO)(PPh3)(2)].0.75CH(3)CN (1), K[PdCl(HnicO)(2)].H2O (2), [Pd(HnicO)(2)(bipy)] (3), cis-[PtCl(HnicO)(PPh3)(2)].0.75CH(3)OH.0.5H(2)O (4), [PtCl(HnicO)(bipy)] (5), cis-[ReOI2(HnicO)(PPh3)] (6), Na-2[Mo2O6(HnicO)(2)].5H(2)O (7), Na-2[Mo4O12(HnicO)(2)].2H(2)O (8) and Na-2[W2O6(HnicO)(2)].5H(2)O (9) have been prepared. The crystal structures of I and 4, were determined by X-ray diffraction and show the HnicO(-) ligand coordinated to palladium or platinum through the nitrogen atom only. Infrared, Raman, H-1 and C-13{H-1} NMR spectroscopic data for the complexes are presented and are in agreement with the crystallographic results. (C) 2002 Elsevier Science Ltd. All rights reserved.
