title: Zinc mercury(II) tetra-kis-(seleno-cyanate).
abstract: 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 seleno-cyanate 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 HgZn4 (or ZnHg4) arrangement is midway between a tetra-hedron and a square plane, with two types of Hg-Zn-Hg (or Zn-Hg-Zn) angles of 92.38 (6) and 156.45 (6)°.
