✦ Synopsis

The title compound, C 11 H 26 P 2 S 2 , displays crystallographic mirror symmetry. Key bond lengths (A Ê ) are P1ÐC(methylene) 1.8464 (18), P1ÐC(butyl) 1.8711 (13), P2ÐC(methylene) 1.8266 (18), P2ÐC(methyl) 1.7948 (15), P1 S 1.9631 (8) and P2 S 1.9552 ( 8), where P1 is the di-tert-butylphosphino P atom and P2 is the dimethylphosphino P atom. The angle PÐ CÐP [124.31 (10) ] is wide and S PÐC(methylene) [108.91 (6) ] narrow. Steric pressure from the tert-butyl groups may cause some of the molecular dimensions to depart from normal values.
