Catena-Poly[[bis-(pyrazine-2-carbox-amide-κN)mercury(II)]-di-μ-bromido].

ABSTRACT: 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 octa-hedral 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. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds are effective in the stabilization of the crystal structure.
