[1,2-Bis(diisopropyl-phosphino)-1,2-dicarba-closo-dodeca-borane-κP,P']dichloridomercury(II).

In the title complex, [HgCl(2)(C(14)H(38)B(10)P(2))], the Hg(II) atom is in a distorted HgCl(2)P(2) tetra-hedral coordination environment. The chelation of the Hg atom by two P atoms and two C atoms from the carborane skeleton results in a nearly planar five-membered ring.
