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)°.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
