Abstract
Mr=274.39, orthorhombic, Pbca, a=7.443 (1), b=32.691 (3), c=11.828 (2) Å, V=2877.98 Å3, Z=8, Dm=1.216 (flotation in KI), Dx=1.266 g cm-3, μ(Cu Kα, λ=1.5418 Å)=17.55 cm-1, F(000)=1152.0, T=293 K, R=6.8%, 1378 significant reflections. (II): Mr=248.35, orthorhombic, P212121, a=5.873 (3), b=13.677 (3), c=15-668 (5) Å, V=1260.14 Å3, Z=4, Dm=1.297 (flotation in KI), Dx=1.308 g cm-3, μ(CuKα, λ=1.5418 Å)=19.55 cm-1, F(000)=520.0, T=293 K, R=6.9%, 751 significant reflections. Crystals of (I) and (II) undergo photo-oxidation in the crystallinestate. In (I) the dihedral angle between the phenyl rings of the biphenyl moiety is 46 (1)° . The C=S bond length is 1.611(5) Å in (I) and 1.630 (9) Å in (II). The correlation between molecular packing and reactivity is discussed.
