Dibromidobis(pyrazine-2-carboxylic acid-?N)mercury(II) dihydrate.

ABSTRACT: The asymmetric unit of the title compound, [HgBr(2)(C(5)H(4)N(2)O(2))(2)]·2H(2)O, contains one half-mol-ecule and one water mol-ecule. The Hg(II) ion, lying on a twofold rotation axis, is four-coordinated by two N atoms of pyrazine-2-carboxylic acid ligands and two bromide ions, forming a highly distorted tetrahedral geometry. In the crystal structure, inter-molecular O-H?O and O-H?N hydrogen bonds link the mol-ecules.

Dibromidobis{1-[4-(pyridin-4-yl)phen-yl]ethanone-?N}mercury(II).

Project description:In the title compound, [HgBr(2)(C(13)H(11)NO)(2)], the Hg(II) atom adopts a four-coordinated HgN(2)Br(2) geometry, formed by two pyridine N atoms from two ligands and two bromide anions. The complex is located on a twofold axis. The coordination geometry is close to forming a see-saw (SS-4) polyhedron, the symmetry-related organic ligands being almost perpendicular; the dihedral angles between the two pyridine rings and between the two benzene rings are 85.5?(4) and 87.7?(4)°, respectively. Within the organic ligand, the pyridine ring is nearly coplanar with the benzene ring [dihedral angle = 13.1?(8)°]. In the crystal, the mol-ecular complexes are connected through weak inter-molecular C-H?Br contacts.
