Description / Table of Contents:
PdSCl, a Molecular Palladium(II) Disulfidechloride with Octanuclear Pd8(S2)4Cl8 Groups and with Tetra Metal-coordinated bridging Disulfide GroupsBlack crystals of PdSCl have been obtained by reaction of Pd with S2Cl2 in closed quartz ampoules at 200°C. The compound is to be formulated as a Palladium(II)-disulfidechloride consisting of Pd8(S2)4Cl8 molecules with approximately D4h symmetry. In the octanuclear complexes Pd atoms form a cube, where bridging disulfide groups are found in front of 4 faces and μ2-bridging Cl atoms on 8 edges. In the monoclinic crystal structure (a = 8.763(2) Å; b = 9.082(2) Å; c = 13.662(4) Å; β = 91.748(23)°; V = 1086.8 Å3; Z = 16 PdSCl; Space gr. P21/n) the molecules form a cubic closed arrangement.
Notes:
Schwarze Kristalle von PdSCl wurden durch Umsetzung von Pd-Metall mit S2Cl2 in geschlossenen Ampullen bei 200°C erhalten. Die Verbindung ist ein Palladium(II)-disulfidchlorid, aufgebaut aus molekularen Pd8(S2)4Cl8-Gruppen mit annähernd D4h-Symmetrie. In den achtkernigen Komplexen bilden Pd-Atome einen Würfel mit S2-Gruppen vor vier Flächen und Cl-Atomen vor 8 Kanten. In der monoklinen Kristallstruktur (a = 8,763(2) Å; b = 9,082(2) Å; c = 13,662(4) Å; β = 91,748(23)°; V = 1086,8 Å3; Z = 16 PdSCl; Raumgr. P21/n) sind die Moleküle kubisch dichtest gepackt.
