Sumario:The title crystal, [HgZn(NCSe)(4)](n), a coordination polymer, has a diamond-like network. In the crystal, the metal ions, Zn(2+) and Hg(2+), are both located on fourfold inversion axes and mimic the role of C atoms in the structure of diamond, and the linear seleno­cyanate bridges replace the C—C bonds. The C—N—Zn unit is almost linear and the C—Se—Hg unit is nearly a right angle. Thus, the HgZn(4) (or ZnHg(4)) arrangement is midway between a tetra­hedron and a square plane, with two types of Hg—Zn—Hg (or Zn—Hg—Zn) angles of 92.38 (6) and 156.45 (6)°.
