Crystals of [Cu(Eddp)center dot(HgCl2)(3)](n) (monoclinic, a = 9.7547(7) angstrom, b = 18.3716(12) angstrom, c = 11.7811(9) angstrom, beta = 94.828(9)degrees, Z = 4, space group P2(1)/n) are made of infinite sheets involving dimeric complexes [Cu-2(Eddp)(2)] interacting with quasi-molecules of HgCl2 (Hg-Cl 2.29-2.36 angstrom). In the dimers, copper atoms are squarely surrounded by two N atoms and two O atoms of the ethylendiamine-N,N'-di(3-propionate) anion, and atom from a neighboring Eddp ion in the apical position; the second apical position is occupied by a Cl atom of one of HgCl2 molecules. Weak Hg-Cl interactions (2.98-3.07 angstrom) join the molecules of HgCl2 in almost planar centrosymmetrical Hg6Cl12 hexamers, and further (Hg-Cl 3.168(3) angstrom, 3.250(2) angstrom) in infinite chains of the hexamers. Finally, the dimeric copper complexes are linked to six Hg atoms of four adjacent hexamers by virtue of their oxygen atoms (Hg-O 2.322(8), 2.609(6) angstrom, 2.730(5) angstrom).
