C18H10S2,M=290.34, monoclinic,P21,a=20.556(5),b=15.843(3),c=3.963(1) Å,ß=92.79(2)° at 18°C,Z=4,Dx=1.496 g cm-3,µ(Cu Ka)=3.53 mm-1. Full-matrix least-squares refinement resulted in a final conventionalR value of 0.036 for 2030 observed reflections. The average C-S bond distance is 1.747(16) Å, the S-S bond length is 2.074(1) Å. The torsion angles at the disulfide group are close to zero, at 3.5 and 0.8°. The carbon frameworks are nearly planar, and closely approximate symmetrymmm. Bond distances are comparable with those in related molecules. |
