The influence of the substituent [PhNHNH- and EtN(NH2)-] on the N-thiophosphorylated thiosemicarbazides RC(S)NHP(S)(OiPr)2 crystal design

Abstract

Two N-thiophosphorylated thiosemicarbazides of the common formula RC(S)NHP(S)(OiPr)2 [R = PhNHNH- (1); EtN(NH2)- (2)] have been synthesized and characterized by IR, 1H and 31P spectroscopy, and the single crystal X-ray diffraction method. Single crystal X-ray diffraction studies showed the thiosemicarbazides form both intra- and intermolecular hydrogen bonds, which in turn lead to polymeric chain formation. Moreover, according to the X-ray data of the phenylsubstituted thiosemicarbazide, the formation of intermolecular H⋯η6-phenyl interactions were established. © 2008 Elsevier Ltd. All rights reserved.
