Inhaltsübersicht. Die S‐verknüpfte Verbindung (OC) 3 CrSPH(CH 3 ) 2 isomerisiert sich oberhalb 25°C zu dem Mercaptophosphan‐Komplex (OC) 5 CrP(CH 3 ) 2 SH. Dieser kristallisiert monoklin in der Raumgruppe P2 1 /c mit den Citterkonstanten a = 6,882, b = 13,290, c = 13,224 Å, β = 91,60° und vier Molekeln in der Elementarzelle. In der Kristallstruktur (R = 0,085) sind die Chromatome pseudooktaedrisch koordiniert von fünf CO‐Gruppen und dem Mercaptophosphanliganden (Cr—P = 2,344 Å). The Behaviour of Mono‐ and Diorganylphosphane Sulphides towards Metal Carbonyl Systems. VIII. Crystal and Molecular Structure of Pentacarbonyl(dimethylmereaptophosphane) chromium Abstract. The S‐linked compound (OC) 5 CrSPH(CH 3 ) 2 isomerizes to the mercaptophosphane complex (OC) 5 CrP(CH 3 ) 2 SH above 25°C. The latter crystallizes monoclinic in the space group P2 1 /c with the lattice constants a = 6.882, b = 13.290, c = 13.224 Å, β = 91.60° and four molecules per unit cell. In the crystal structure (R = 0.085) the chromium atoms are pseudooctahedrally coordinated by five CO groups and the mercaptophosphane ligand (Cr—P) = 2.344 Å).
