• The crystal and molecular structure of the title metal complex was determined by the X-ray diffraction method. The crystal is triclinic, with the space group P\bar1, <I>Z</I>=1, <I>a</I>=11.934(2), <I>b</I>=14.642(9), <I>c</I>=11.801(6)Å, α=90.41(5), β=94.04(2), and γ=83.82(2)°. The final <I>R</I> value for 6928 reflections is 0.065. The cobalt(II) ato is in a tetrahedral geometry, ligated by four nitrogen atoms of the thiocyanato (SCN) ligands, while the mercury(II) atom is in a trigonal-bipyramidal geometry, where two phosphorus atoms of both the triphenylphosphine ligands bond axially and three sulfur atoms of SCN's equatorially; however, these Hg–S bonds are very long. Thus, the pairs of cobalt(II) and mercury(II) atoms are linked by one SCN bridge, forming a sixteen-membered ring of Co<SUB>2</SUB>Hg<SUB>2</SUB>(SCN)<SUB>4</SUB>, and this ring is linked with the next ones on both sides in the a-axis direction with two longer bondings.
