catena-Poly[[bis(pyridine-3-carboxylic acid-κN)mercury(II)]-di-μ-chlorido]

In the title compound, [HgCl2(C6H5NO2)2]n, the HgII cation is located on an inversion center and is six-coordinated in a distorted octahedral geometry by two N atoms from two pyridine-3-carboxylic acid molecules and four bridging Cl− anions. The bridging function of the Cl− anions leads to polymeric chains running along the a axis. One Hg—Cl bond is much longer than the other. In the crystal, O—H...O and weak C—H...Cl hydrogen bonds are observed.
