Abstract: | Crystal Structure of MgHg(SCN)4 · 2 H2O The crystal structure of the monoclinic MgHg(SCN)4 · 2 H2O (a ? 1 335.1(6) pm, b ? 531.6(5) pm, c ? 1 867.0(14) pm, β ? 92.3(1)°, Z ? 4, space group C2/c) contains nearly tetrahedral Hg(SCN)4 and octahedral Mg(OH2)2(NCS)4 groups. These groups are joined together with Hg? SCN? Mg bridges and are forming a network of layers. |
