Nanoparticles of two new coordination supramolecular compounds, [Hg2(L)2(Br)4]n (class="boldFont">1) and [Hg(L′)(SCN)2] (class="boldFont">2), have been synthesized by use of a sonochemical process.
The single crystal X-ray data of compounds class="boldFont">1 and class="boldFont">2 imply that the Hg(II) ions are four and five coordinated, respectively.
The role of temperature, reaction time and ultrasound irradiation power on the size and morphology of nano-structures class="boldFont">1 and class="boldFont">2, have been investigated.
Increase of temperature, sonication power and decrease in reaction time leads to a decrease of particle size.
