By means of X-ray diffraction the chain structure of [Cu(l-Arg)(2)]Hg2Cl6 (monoclinic, a = 10.2348(9) angstrom, b = 9.1386(7) angstrom, c = 14.8521(14) angstrom, beta = 97.455(11)degrees, space group P2(1)) is established. The chains are formed by square-planar [Cu(l-Arg)(2)](2+) cations of the type trans-[Cu(N)(2)(O)(2)] (l-Arg is the zwitter-ion of arginine; Cu-N 1.992 angstrom and 1.938(6) angstrom, Cu-O 1.953 angstrom and 1.967(4) angstrom) that are bonded to two adjacent binuclear [Cl2Hg(mu-Cl)(2)HgCl2](2-)ions through its clorine atoms Cl (Hg-Cl bonds are within 2.34-2.78 angstrom). With these two additional Cu center dot center dot center dot Cl contacts Cu adopts the geometry of an elongated octahedron with two apical Cl (Cu-Cl 2.961 angstrom and 3.064(3) angstrom).
