Abstract
The crystal structure of the title compound PhAs(S2COPri)2 has been determined by single crystal X-ray diffraction and refined by full matrix least squares analysis with anisotropic temperature factors. The crystal is monoclinic, space groupP21/c,a=8.889(6),b=16.174(19),c=13.506(14) Å,β=102.02(7)°,V=1899.2 Å3,Z=4,D c=1.478 g cm−3, monochromated Mo-Kα radiation, λ=0.71069 Å,μ=22.07 cm−1.
The geometry around the arsenic atom is square pyramidal. Each ligand is bonded to an arsenic atom through two unequal As-S bonds measuring 2.298 and 3.041 Å. The apical position is occupied by a phenyl group and a lone pair of electrons is presenttrans to the phenyl group.
