Sumario:In the title organometallic polymer, [HgCl(2)(C(26)H(20)NO(3)P)](n), the monodentate 1-(3-nitro­phen­yl)-2-(triphenyl­phospho­ran­yl­­idene)ethanone ligand is coordinated to the Hg(II) atom through the methine C atom. The Hg(II) atom is four-coordinated in a distorted tetra­hedral geometry by one terminal Cl atom, two bridging Cl atoms, and one C atom from the ylidic ligand, resulting in a polymeric chain parallel to [010]. The terminal Cl atom is more strongly bound to the Hg(II) ion [2.3916 (9) Å] than the bridging Cl atoms. The bridge is asymmetric, as indicated by the two different Hg—Cl(bridging) bond lengths [2.5840 (8) and 2.7876 (8) Å]. Intra­molecular C—H⋯O and weak C—H⋯Cl contacts stabilize the polymeric chain. In the crystal, adjacent chains inter­act via C—H⋯O hydrogen bonds.
