N,N′-(Ethane-1,2-diyl)dibenzenecarbothioamide

Abstract

Key indicators: single-crystal X-ray study; T = 223 K; mean (C-C) = 0.002 Å; R factor = 0.029; wR factor = 0.083; data-to-parameter ratio = 15.3.The title compound, C 16 H 16 N 2 S 2 , adopts a gauche) conformation in the NH-CH 2 -CH 2 -NH bond sequence. In the crystal, molecules are connected by pairs of N-HÁ Á ÁS C hydrogen bonds and C-HÁ Á Á interactions, forming a tape structure along the c-axis direction. Related literature

Structure–property relationships of aromatic polyamides and polythioamides: comparative consideration with those of analogous polyesters, polythioesters and polydithioesters

“…8, lms of PTA2T and PTA3T were cast on small Petri dishes from the DMF solutions; therefore, the polythioamides have molecular weights high enough to form the lms, which are optically translucent and brown in color. The crystal structures of 2DBA and 3DBA were determined by Brisse et al, 33,34 and those of 2DBTA and 3DBTA by us 35,36 (see Fig. 9).…”
