catena-Poly[[bis­(pyrazine-2-carbox­amide-κN (4))mercury(II)]-di-μ-bromido]

In the crystal structure of the title compound, [HgBr(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) cation is located on an inversion center and is coordinated by two N atoms from the pyrazine rings and four bridging Br(−) anions in a distorted octa­hedral geometry. The Br(−) anions bridge the Hg(II) cations...

description In the crystal structure of the title compound, [HgBr(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) cation is located on an inversion center and is coordinated by two N atoms from the pyrazine rings and four bridging Br(−) anions in a distorted octa­hedral geometry. The Br(−) anions bridge the Hg(II) cations with significantly different Hg—Br bond distances of 2.4775 (8) and 3.1122 (8) Å, forming polymeric chains running along the a axis. Inter­molecular N—H⋯O and N—H⋯N hydrogen bonds are effective in the stabilization of the crystal structure.
