Abstract

Abstract Synthesis, spectroscopic studies and single crystal X-ray structure of [Pd(Hafdo)2], where H2afdo is α-furilglyoxime, were carried out because of its potential columnar stack structure and the existence of a short intramolecular hydrogen bond. The compound crystallizes in the orthorhombic space group Pnab with a=6.930(3), b=14.286(2) and c=19.837(4) A. The intensity data were collected on a CAD-4 diffractometer and the structure was refined to a final R value of 6.1%. The central metal atom in this inner complex has planar geometry and the oxime oxygen atoms are involved in a short intramolecular hydrogen bond with O[sbnd]O distance of 2.583(4) A. The complex molecules are stacked above one another along the crystallographic a axis with adjacent molecules rotated 90° with respect to each other. The Pd-Pd distance is 3.465(4) A. The two oxygen atoms of the planar furane groups are separated by 2.686(4) A and the furane rings are oriented at an angle of 46.7° with respect to each other. The columna...
