Abstract
|
A novel nano-structures mercury(II) coordination compound, [Hg (HPCIH) I2] (1), (‘‘HPCIH’’ is the abbreviation of 2-pyridinecarbaldehyde isonicotinoyl hydrazone) has been synthesized by a hydrothermal method that produces the coordination compound at nano size. The new nanostructure was characterized by transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction elemental analysis and IR spectroscopy. Compound 1 was structurally characterized by single crystal X-ray diffraction and the single-crystal structure of this complex shows that each mercury(II) center is five coordinated with two N-donor and one O-donor atoms from ‘‘HPCIH’’ ligand and two iodo anions. Self-assembly of this complexes is realized by CHI, II and p–p stacking interactions. The supramolecular features in these complexes are controlled by weak directional intermolecular interactions.
