    Description / Table of Contents: Crystal Structure of MgHg(SCN)4 · 2 H2OThe 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.

    Description / Table of Contents: Crystal Structure of SrHg(SCN)4 · 3 H2OSrHg(SCN)4 · 3 H2O is orthorhombic, space group Pcca, with a = 19.476(7), b = 8.150(1), c = 8.991(3) Å, V = 1427.1 Å3, Z = 4, dc = 2.67 g · cm-3, μ(AgKα) = 77.95 cm-1.The salt consists of nearly tetrahedral Hg(SCN)4 groups, Sr has a tricapped trigonal prismatic coordination: four N and five O atoms. The thiocyanate groups form end-to-end bridges and connect the Hg and Sr coordination polyhedra.
    Notes: SrHg(SCN)4 · 3H2O ist orthorhombisch, Raumgruppe Pcca, mit a = 19,476(7), b = 8,150(1), c = 8,991(3) Å, V = 1427,1 Å3, Z = 4, dc = 2,67 g · cm-3, μ(AgKα) = 77,95 cm-1.In der Verbindung sind annähernd tetraedrische Hg(SCN)4-Einheiten enthalten. Sr besitzt eine tricapped trigonal prismatische Koordination (4 N- und 5 O-Atome). Die Thiocyanatogruppen liegen als end-to-end-Brücken vor und verbinden die beiden Koordinationspolyeder.

    Description / Table of Contents: On the Dicyanothiocyanatomercurates(II) of the Alkaline-earth MetalsThe reactions between Hg(CN)2 and M(NCS)2 · nH2O (M = Mg, Ca, Sr, Ba; n = 3, 4) in aqueous solutions lead to the compounds M[Hg(CN)2SCN]2 · 4 H2O. The compounds yielded by crystallization are characterized with x-ray, spectroscopic, and thermal methods. The crystal structures of Mg[Hg(CN)2SCN]2 · 4 H2O and Sr[Hg(CN)2SCN]2 · 4 H2O have been determined by x-ray structure analysis. These structures can be compared with the compounds M′Hg(CN)2SCN (M′ = K, Rb, Cs).
    Notes: Durch Reaktion zwischen Hg(CN)2 und den Erdalkalithiocyanaten M(NCS)2 · nH2O (M = Mg, Ca, Sr, Ba; n = 3, 4) in H2O wurden die Verbindungen M[Hg(CN)2SCN]2 · 4H2O dargestellt. Die kristallinen Spezies wurden durch röntgenographische, spektrometrische und thermische Methoden charakterisiert. Die Strukturen der Verbindungen mit M = Mg und Sr konnten bestimmt werden. Der strukturelle Aufbau läßt Vergleiche mit den entsprechenden Verbindungen der Alkaliionen M′Hg(CN)2SCN (M′ = K, Rb, Cs) zu.

    Description / Table of Contents: Crystal Structure of BaHg(CN)4 · 4 PyridineThe structure of the tetragonal BaHg(CN)4 · 4 Pyridine (space group I4, a = 1119.4(7), c = 1 057.9(7) pm, Z = 2, dc = 1.87 g · cm-3) contains tetrahedral Hg(CN)4 and bisdisphenoide Ba(NC)4(py)4 groups, which are linked together by Hg—CN—Ba bridges. The BaHg(CN)4 framework consists of a 3-dimensional network of all round edge-sharing tetrahedrons. The analogous strontium compound is isotype with a = 1 108.2(9) and c = 1 035.3(14) pm.

Dem BaHg(CN)4-Gerüst liegt ein Aufbau aus allseitig eckenverknüpften Tetraedern zugrunde. Die analoge Strontium-Verbindung ist isotyp mit a = 1 108,2(9) und c = 1 035,3(14) pm.
