文摘

A series of novel complexes, dihalo-bis(N-p-anisoyl-2-oxo-1-naphthylideneamine-O)zinc(II) (1, 2, 3) and di-μ-halo-bis[halo(N-p-anisoyl-2-oxo-1-naphthylideneamine-O)mercury(II)] (4, 5, 6), of the general formulae [ZnX2(LH)2] and [HgX2(LH)], X = Cl, Br, I, have been prepared. The crystal structure of 1 reveals the four-co-ordinated zinc center by two halogen atoms and two oxygen atoms from neutral monodentate Schiff-base ligand in the form of distorted tetrahedron. Mercury atom in the asymmetric unit of mercury adduct 6 is co-ordinated with two iodine atoms and one oxygen atom from neutral monodentate Schiff-base ligand. The HgI2(LH) moieties are linked into 1D polymeric chains via Hg⋯I contacts.The UV–Vis spectra of the adducts obtained in the ethanolic solution as well as the results of the 1H and 13C NMR measurements performed in d6-dmso indicate that adducts undergo the decomposition after dissolving.
