The synthesis, crystal and molecular structures of two saccharinate–metal complexes with dipyridylamine (dipyr) as a co-ligand
چکیده انگلیسی

The complexes [Cd(dipyr)2(sac)(H2O)] sac·H2O 1 and [Hg(dipyr)(sac)2] 2, where dipyr = dipyridylamine and sac = saccharinate, have been synthesised, and fully characterised by single-crystal X-ray diffraction at 120 K. The geometry around Cd in 1 is approximately octahedral, with the metal coordinated by two bidentate dipyr ligands, one N-bonded sac and one H2O molecule; the second sac forms the counter-ion, and there is also a water of crystallisation. An extensive H-bonded network is formed. In the anhydrous Hg complex 2, the metal has approximately tetrahedral geometry, with coordination from a bidentate dipyr ligand and two N-bonded sac groups. H-bonding interactions are again extensive, even without the presence of H2O molecules in the structure, leading to chains along the a-axis.

Two new saccharinate–metal (Cd or Hg) complexes with dipyridylamine (dipyr) as a co-ligand have been fully characterised by single-crystal X-ray diffraction at 120 K. The dipyr ligand coordinates in a bidentate fashion.Figure optionsDownload as PowerPoint slide
