Professor Ulrich Mu È ller zum 60. Geburtstag gewidmet.Inhaltsu È bersicht. (Hg 6 As 4 )[MoCl 6 ]Cl wird aus Hg 2 Cl 2 , Hg, As und MoCl 4 in evakuierten, geschlossenen Glasampullen im Temperaturgefa È lle 450 ® 400°C in Form tiefroter, wu È rfelfo È rmiger Kristalle erhalten. (Hg 6 As 4 )[TiCl 6 ]Cl und (Hg 6 As 4 )[TiBr 6 ]Br entstehen ebenfalls in geschlossenen, evakuierten Ampullen aus Hg 2 X 2 (X = Cl, Br), Hg, As und Ti-Metall bei 275°C bzw. 245°C in Form dunkelgru È ner bzw. schwarzer Kristalle. Alle drei Substanzen sind luft-und lichtempfindlich und kristallisieren isotyp (kubisch, Pa 3, a = 1207,8(4) pm fu È r (Hg 6 As 4 )[MoCl 6 ]Cl, a = 1209,4(3) pm fu È r (Hg 6 As 4 )[TiCl 6 ]Cl, a = 1230,9(3) pm fu È r (Hg 6 As 4 )-[TiBr 6 ]Br, Z = 4). Die Strukturen bestehen aus einem dreidimensional verknu È pften Hg±As-Geru È st, das aus As 2 -Gruppen (As±As-Abstand im Mittel 242 pm) aufgebaut ist, die jeweils u È ber sechs Hg-Atome mit sechs weiteren As 2 -Gruppen verbunden sind. Auf diese Weise entstehen in dem polykationischen (Hg 6 As 4 )-Geru È st Hohlra È ume, deren eine, gro È ûere Sorte mit oktaederfo È rmigen [MoCl 6 ] 3± , [TiCl 6 ] 3± bzw.[TiBr 6 ] 3± -Ionen und deren zweite, kleinere Sorte mit diskreten Halogenid-Ionen gefu È llt ist. Die magnetischen Eigenschaften der beiden Ti-haltigen Substanzen lassen sich mit einem d 1 -Paramagnetismus und der Beru È cksichtigung der Spin-Bahn-Kopplung nach Figgis deuten.

Polycationic Hg±As Frameworks with Trapped Anions. II [1]Synthesis, Crystal Structure, and Magnetism of (Hg 6 As 4 )[MoCl 6 ]Cl, (Hg 6 As 4 )[TiCl 6 ]Cl, and (Hg 6 As 4 )[TiBr 6 ]Br Abstract. (Hg 6 As 4 )[MoCl 6 ]Cl is obtained by reaction of Hg 2 Cl 2 , Hg, As, and MoCl 4 in closed, evacuated glass ampoules in a temperature gradient 450 ® 400°C in form of dark red cubelike crystals. (Hg 6 As 4 )[TiCl 6 ]Cl and (Hg 6 As 4 )-[TiBr 6 ]Br are also formed in closed, evacuated ampoules from Hg 2 X 2 (X = Cl, Br), Hg, As, and Ti metal at 275°C and 245°C in form of dark green and black crystals, respectively. All three compounds are air and light sensitive. They crystallize isotypically (cubic, Pa 3, a = 1207.8(4) pm for (Hg 6 As 4 )-[MoCl 6 ]Cl, a = 1209.4(3) pm for (Hg 6 As 4 )[TiCl 6 ]Cl, a = 1230.9(3) pm for (Hg 6 As 4 )[TiBr 6 ]Br, Z = 4). The structures consist of a three-dimensionally connected Hg±As framework which is made up of As 2 groups (As±As distance averaged 242 pm) each connected via six Hg atoms to six neighbouring As 2 groups. There are two cavities of different size in the polycationic framework. The bigger cavity is filled with [MoCl 6 ] 3± , [TiCl 6 ] 3± , and [TiBr 6 ] 3± ions of nearly ideal octahedral shape, the smaller cavity with discrete halide ions. The magnetic properties of the two Ti containing compounds are in accordance with a d 1 paramagnetism. The temperature dependence and the magnitude of the magne...

A novel host–guest compound [Hg7As4I3](SnI3) has been prepared by a standard ampoule technique and its crystal structure was determined. It crystallizes in a cubic system [space group P213, a = 13.110(1) Å, Z = 4] with a unique structure type. The crystal structure comprises two parts: the three‐dimensional [Hg7As4I3]1+ host network, and the SnI31– guest anions encapsulated in the cavities of the network. The network is built from the As2Hg7 bitetrahedra and As2Hg6 octahedra, which share corners, and contains an additional iodine atom connected to one of the mercury vertices. The SnI31– anion has the shape of a pyramid with the tin atom in a vertex. According to the quantum‐chemistry calculations, the geometry of the anion deviates substantially from the equilibrium one, and is influenced by the distant mercury atoms of the host network.

Two new metal pnictide halides, (Hg(9.75)As(5.5))(GaCl4)3 and (Hg13Sb8)(ZnBr4)4, have been prepared by solid-state reactions. Their structures feature 3D cationic host frameworks built of mercury pnictide polyhedra and form 1D tunnels filled with discrete guest halide polyanions; the guests and hosts are assembled by van der Waals interactions. Both complexes exhibit good single-crystal humidity sensitivity, with a humidity sensitivity factor as big as three orders of magnitude, a quick resistance response, fast recovery, and good reproducibility. This study provide a new way to design promising resistive humidity detectors by introducing van der Waals host-guest interactions into their structures.
