SYNTHESIS, CRYSTAL-STRUCTURE AND SPECTROSCOPIC CHARACTERIZATION OF THE COMPLEX OF PALLADIUM(II) WITH TRIS(2-PYRIDYLMETHYL)AMINE

A complex of palladium(II) chloride with tris(2-pyridylmethyl) amine ( TPA) has been synthesized and characterized. The single-crystal struct ure has been determined by Xray diffraction analysis. The palladium(II ) atom in the title complex is in a square planar environment surround ed by three nitrogen atoms of TPA and one chlorine atom, with bond len gths in the range of 2.094-2.012 Angstrom for d-N and 2.296 Angstrom f or Pd-Cl. The properties of [Pd((TPA)Cl)]. ClO4 have been further stud ied with IR and UV-vis techniques. IR spectra show that most of the ba nds of [Pd((TPA)Cl)]. ClO4 are shifted to lower wavenumbers in compari son with those of the TPA ligand. Copyright (C) 1996 Elsevier Science Ltd
