Catena-Poly[[bis-(pyridine-3-carb-oxy-lic acid-?N)mercury(II)]-di-?-chlorido].

ABSTRACT: In the title compound, [HgCl(2)(C(6)H(5)NO(2))(2)](n), the Hg(II) cation is located on an inversion center and is six-coordinated in a distorted octa-hedral geometry by two N atoms from two pyridine-3-carb-oxy-lic acid mol-ecules 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.
