The complete molecule of the title complex, [Hg(C 11 H 11 N 4 O 2 S) 2 (C 10 H 8 N 2 )], is generated by crystallographic twofold symmetry, with the mercury cation lying on the rotation axis. The mercury coordination polyhedron can be described as tetrahedral (from the N , N ′-bidenate bipyridine molecule 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 molecules into a three-dimensional network.
