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

Two N-thiophosphorylated thiosemicarbazides of common formula RC(S)NHP(S)(Oipr)2 [R=PhNHNH-(1); EtN(NH2)-(2)] were synthesized and characterized. Single crystal X-ray diffraction studies showed the thiosemicarbazides to form both intra- and intermolecular hydrogen bonds which in turns lead to the polymeric chains formation. Moreover, according to the X-ray data of the phenylsubstitueted thiosemicarbazide it was established the formation of the intermolecular H⋯η6-phenyl interactions.
