  Complexes of zinc(II) halides with N-benzyl- and N-p-tolyl-2-oxo-1-naphthylideneamine – preparation and characterization

  摘要：

  A series of novel complexes, dihalo-bis(N-benzyl-2-oxo-1-naphthylideneamine-O)zinc(II), ZnX2(bznapH)(2) (1-3), dihalo-bis(N-p-tolyl-2-oxo-1-naphthylideneamine-O)zinc(II), ZnX2(tolnapH)(2) (4-6), of the general formula [ZnX2(LH)(2)] X = Cl, Br, I, have been prepared. The crystal structures of four compounds (1-4) reveal four coordinated zinc centres by two halogen and two oxygen atoms from the Schiff-base in the form of distorted tetrahedra. Complex 4 crystallizes as the one-to-one solvate with ethanol.The tetrahedral distortion is most pronounced in the structure of ZnI2(bznapH)(2) complex. X-ray structural data showed that the Schiff-base ligand in the naphthylideneamine tautomeric form is weakly bound to Zn atom in 1-4 (being in the range from 1.952(3) Angstrom in 2 to 2.002(3) Angstrom in 4). The molecular structures of 1-4 are governed by the type of halide and the corresponding Schiff-base. Although the structure comparison of ZnX2(bznapH)(2) vs. ZnX2(tolnapH)(2) leads to the conclusion that ligand spatial accomodation (non-planar bznapH with aliphatic interruption vs. aromatic: tolnapH) is the dominating factor in the crystal structures. The crystal structures of 2-4 are dominated by van der Waals forces. There is a weak intermolecular hydrogen bond of the C-(HCl)-Cl-... type in 1 (3.710(5) Angstrom joining molecules into endless chains. The UV-Vis and H-1 NMR spectra, obtained in ethanolic and acetone solution indicate that the complexes do not exist in the solutions. (C) 2004 Elsevier Ltd. All rights reserved.
