Notes:
The reaction of the ligand cis - -S—C(Ph)≡C(Ph)-S-[CH2]n - S - C(Ph)=C(Ph)-S- with n=3 (dianion of 1) with HgCl2 in ethanol produces a yellow linearly trinuclear, μ1-S and μ1-Cl-bridged complex of composition C62H52Cl2Hg3S8 (4), in which the central Hg(II) ion is in a near octahedral arrangement of four Hg—S and two Hg—Cl bonds, whereas the two terminal Hg(II) ions are tetracoordinated with three Hg—S bonds and one Hg—Cl bond in distorted tetrahedral arrangements. The two ligands are bidentate with respect to the terminal and central Hg(II) ions. The corresponding ligand with n=4 (dianion of 2) reacts with HgCl2 to yield a yellow Hg(II) complex of composition C32H28HgS4 (5), in which the ligand is tetradentate and in the trans-syn configuration. The Hg(II) ion in the unit cell of 5 is pentacoordinated, due to symmetric dimerization of two molecules of 2 by two weak coordinate Hg—S bonds of 3.442(2) Å length.
