Synthesis and crystal structures of bis(N-phenyl-3,5-dinitrothiobenzamidato)mercury(II) and bis(N-phenyl-4-nitrothiobenzamidato)mercury(II)

Abstract

The crystal structures of bis(N-phenyl-3,5-dinitrothiobenzamidato)mercury(II) (1) and bis(N-phenyl-4-nitrothiobenzamidato)mercury(II) (2) have been determined by single-crystal X-ray diffraction. Both the complexes crystallize in centrosymmetric monoclinic space groups with crystallographic inversion symmetry. The S-Hg-S linkage is thus precisely linear in each case. Significant secondary interactions include intramolecular Φ coordination by phenyl groups, aromatic ring stacking in the case of 1 only, and a number of intramolecular and intermolecular C-H...X contacts (X=O, N, S) influencing the molecular conformation and crystal packing. © 2010 Taylor & Francis.
