A twist between the terminal benzene ring and the hydrazine residue is seen [N - N - C - C torsion angle = 163.81 (12)°]. Helical supra-molecular chains along the c axis mediated by N - H⋯O hydrogen bonds are the most prominent feature of the crystal packing. The chains are connected into layers lying in the ac plane by weak C - H⋯π contacts involving two methyl-ene H atoms and an adjacent benzene ring.  ISSN : 1600-5368  Journal Name : Acta Crystallographica Section E: Structure Reports Online  Volume : 67  Issue Number : 8  Publishing Year : 1432 AH 2011 AD  Article Type : Article  Added Date : Saturday, December 10, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email Hatem A Abdel-Aziz Abdel-Aziz, Hatem A Researcher Doctorate hatem_741@yahoo.com Seik Weng Ng Ng, Seik Weng Researcher Doctorate seikweng@um.edu.my E R T Tiekink Tiekink, E R T Researcher Doctorate edward.tiekink@gmail.com Files File Name Type Description  31614.pdf pdf Abstract Back To Researches Page
