catena-Poly[[(2-amino­pyrimidine-κN¹)(thio­cyanato-κS)mercury(II)]-μ-thio­cyanato-κ²S:N]

In the title coordination polymer, [Hg(NCS)₂(C₄H₅N₃)], the Hg^II atom is four-coordinated by one aromatic N atom from a 2-amino­pyrimidine ligand, one S atom from a terminal thio­cyanate ligand, and one S atom and one N atom from a bridging thio­cyanate ligand. The crystal structure features polymeric chains running along the b axis which are stabilized by N—H...N hydrogen bonds.
