Cluster compounds mercury-containing

When mercury bis[benzenetellurolate], bis[triorganophosphane]mercury perchlorate, and triorganophosphane were stirred in dichloromethane, chloroform, or acetone at 20°, cluster compounds of mercury containing tellurolate and phosphane ligands were formed2. 

The development of the second class of compounds with gold-mercury bonds, that is, Hg-containing, Au-rich clusters, was mainly the contribution of Pignolet and coworkers [41-43]. Such compounds were generally obtained by addition of mercury... 

There are three important routes to the formation of the mercury-transition metal bond (a) displacement of halogen or pseudohalogen from mercury(II) salts with carbonyl metallate anions (b) reaction of a halo-phenylmercury compound with a transition metal hydride and (c) oxidative addition of a mercury halide to neutral zero valent metals.1 We report here the syntheses of three compounds containing three-centre, two-electron, mercury-ruthenium bonds utilizing trinuclear cluster anions and mercury(II) halides.2-4... 

Mercury will bond directly to certain metal atoms including Co, Ru, Rh, Fe, Pt, and Mn. Such Hg-metal bonds are usually part of linear M-Hg-M or M-Hg-X linkages, and some clusters containing mercury-metal bonds are also known. These compounds are prepared by the reaction of mercury(II) halides with carbonyhnetallates. A rare example of trigonal prismatic (see Trigonal Prism) coordination in a mercury complex is exhibited by [Hg Pt3(2,6-Me2C6H3NC)6 2], which contains Pt-Hg bonds. These types of compound have been reviewed. ... 

The first example of a solid compound (Na3Hg2 amalgam) containing doubly cr- and 7T-aromatic transition metal cluster Hg " was discovered by Kuznetsov et al. [27]. Formation of the Hg " cluster was puzzling since mercury has a closed shell electron configuration (6s ), and therefore a neutral Hg4 cluster is expected to be a van der Waals complex. The stability of the Hg " building block can be explained due to the fact that it is isoelectronic to the first all-metal aromatic cluster.
