Abstract

Phosphorus-Centered and Phosphinidene-Capped Tungsten Chloride Clusters.-The new P-centered W6PCl17 (I) cluster compound is prepared by reduction of WCl6 with red phosphorus (evacuated silica tube, 370°C, 24 h; 95% yield estimated from XRD). When the reduction is performed at 500°C, the phosphinidene-capped cluster compound W4(PCl)Cl10 (II) is produced in 95% yield (from XRD). The structure of (I) (orthorhombic, space group Imm2, Z = 2; powder XRD) contains chains of chloride-bridged W6PCl17 hexanuclear clusters that form a hexagonal stick packing structure. The structure of (II) (monoclinic, C2/m, Z = 4; single crystal XRD) features a Jahn-Teller distorted tetranuclear tungsten cluster that is interconnected to a layered structure. -(STROEBELE, M.; EICHELE, K.; MEYER*, H.-J.; Eur.
