In the title crystal structure, C 14 H 14 S 2 , L 2 , the molecules lie on crystallographic inversion centers. The phenyl rings are nearly perpendicular to the planar S-C-C-S group of atoms.
In the title compound, C 14 H 14 S 2 , there is a centre of inversion at the mid-point of the central C-C bond. Excluding H atoms, the molecule adopts an anti conformation, with a planar -S-CH 2 -CH 2 -S-spacer unit. The dihedral angle between the phenyl ring and the S-C-C-S chain is 84.52 (18) .
The crystal structure of 1,2-bis(2-aminophenoxy)ethane, C 14 H 16 N 2 O 2 , exhibits intermolecular close contacts between the amine groups and O atoms of neighbouring molecules. In addition, weak C-HÁ Á ÁO hydrogen-bonding interactions are present. A crystallographic twofold axis bisects the centra
