Abstract

Colourless single crystals of [Hg₂(Pym)](NO₃) ₂, [Hg₂(Pym)](ClO₄)₂ und [Hg ₂(Pyp)₂](ClO₄)₂ were obtained from aqueous solutions of the respective components Hg₂(NO ₃)₂·2H₂O, Hg₂(ClO ₄)₂·6H₂O, pyrimidine (Pym) and pyrazine (Pyp). The crystal structures were determined from single-crystal X-ray diffractometer data. [Hg₂(Pym)](NO₃)₂: monoclinic, C2/c, Z = 8, a = 1607.4(2), b = 652.79(7), c = 2000.5(2) pm, β = 103.42(2)°, R_all = 0.0530; [Hg₂(Pym)](ClO ₄)₂: orthorhombic, Pnma, Z = 4, a = 1182.7(2), b = 1662.5(2), c = 607.9(1) pm, R_all = 0.0438; [Hg₂(Pyp) ₂](ClO₄)₂: orthorhombic, Aba2, Z = 4, a = 1529.39(9), b = 1047.10(14), c = 1133.49(15) pm, R_all = 0.0381. The crystal structures of [Hg₂(Pym)](NO₃)₂ and [Hg₂(Pym)](ClO₄)₂ contain polymeric cationic chains [Hg₂(Pym)]⁺ that are arranged to corrugated layers between which the anions are situated. [Hg₂(Pyp) ₂](ClO₄)₂ consists of polymeric cationic layers that are built from (Hg₂)₂(Hg₂) _2/2(Pyp)₄ rings connected to each other; the perchlorate tetrahedra are located between these layers.
