dc.abstract.en Two novel cadmium(II) complexes with homologous pyridine alcohols: [Cd(2-MeOHPy) 2 (NO 3 ) 2 ]( 1 ) and [Cd(2-EtOHPy) 2 (NO 3 ) 2 ]( 2 ) have been prepared and characterized by elemental analysis, X-ray crystallo- graphic studies, spectroscopic (IR, 1 H and 13 C NMR) and thermal properties. IR, NMR and X-ray analysis have confirmed a bidentate fashion of coordination of heteroaromatic alcohols with Cd(II) ions. 2-MeO- HPy bound directly to the central ion by N, O-donor atoms giving five-membered chelate ring but 2- EtOHPy formed less stable six-membered chelate ring. In the complex ( 1 ) and ( 2 ) bidentate nitrate ligands are arranged in cis position for organic ligands. In both cases cadmium(II) ions are eight-coordi- nated and shape of coordination polyhedral can be described as pseudo-dodecahedron (CdN 2 O 6 chromo- phore type). The crystal packing of Cd(II) complexes are stabilized by intermolecular classical hydrogen bonds of O A H O and non-classical C A H O type. In addition, there are p – p stacking interactions between almost parallel-displaced pyridine rings of 2-hydroxymethylpyridine in the two neighbouring complex ( 1 ) molecules but the hydrogen interactions in ( 2 ) are formed by C A H donor group of Py rings and p -electron system of neighbouring one. pl
