摘要：

The synthesis of two [Hg(L1)(2)] and [Hg(L2)(2)] complexes using asymmetric triazenes as ligands are reported. The triazene ligands are substituted with cyano and chloride groups in the ortho positions of the aryl rings (where HL1 and HL2 are 1-(2-ethoxyphenyl)-3-(2-cyanophenyl)triazene and 1-(2-ethoxyphenyl)-3-(2-chlorophenyl) triazene, respectively). These complexes were prepared by the reaction of corresponding triazenes with Hg(NO3)(2) and were characterized by FT-IR, NMR, elemental and single crystal X-ray analyses. Both triazene ligands were found to deprotonate on coordination and act as tridentate chelating ligands forming distorted N4O2 octahedral geometry around Hg-II atoms. Hydrogen bonds, pi center dot center dot center dot pi and C-H center dot center dot center dot pi stacking interactions help to the stabilization of the resulted frameworks. (C) 2012 Elsevier Ltd.
