Abstract
In the title organometallic polymer, [HgCl2(C26H20NO3P)]n, the monodentate 1-(3-nitrophenyl)-2-(triphenylphosphoranylidene)ethanone ligand is coordinated to the HgII atom through the methine C atom. The HgII 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 HgII 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.
