  Structural diversity in mercury(II) coordination complexes with asymmetrical hydrazone-based ligands derived from pyridine

  摘要：

  Three novel Hg(II) complexes 1-3 of asymmetrical hydrazone-pyridine based ligands, L-1-L-3, with distinct coordination structures have been prepared and characterized by a single crystal X-ray diffraction, elemental and thermal analysis, and IR spectroscopy. The complexes form either discrete units with one (1) or two (2) organic ligands, or one-dimensional polymers (3). Hence the ligands can be regarded as chelating (1), mono-dentate (2) or bridging (3) agents. The mercury center is essentially neutralized in each complex by two iodide anions. The coordination in complexes 2 and 3 adopts deformed tetrahedral shapes. In contrast the Hg(II) cation in complex 1 binds three coplanar ligating atoms (O,N,N) and, as with pincer ligands, its coordination polyhedron is supplemented with two I- anions in apical positions. The structural diversity in these complexes is strongly influenced by the position of N atom in pyridine derived moieties. The crystal structure is stabilized by N/O-H center dot center dot center dot N/O/I hydrogen bonds and pi center dot center dot center dot pi interactions. (C) 2015 Elsevier B.V.
