Bis[4-amino-N-(4-methyl-pyrimidin-2-yl-κN (3))benzene-sulfonamidato-κN](2,2'-bi-pyridine-κ(2) N,N')mercury(II).
The complete mol-ecule of the title complex, [Hg(C11H11N4O2S)2(C10H8N2)], is generated by crystallographic twofold symmetry, with the mercury cation lying on the rotation axis. The mercury coordination polyhedron can be described as tetra-hedral (from the N,N'-bidenate bi-pyridine mol-ecule and the sulfonamide N atoms of the sulfamerazine anions) or as squashed trigonal-prismatic, if two long (> 2.80 Å) Hg-N bonds to pyrimidine N atoms are included. The dihedral angle between the aromatic rings in the anion is 73.3 (2)°. In the crystal, N-H⋯(N,O) and N-H⋯N hydrogen bonds link the mol-ecules into a three-dimensional network.
