4-phenylthiosemicarbazone ( 2 ). Both compounds were fully characterised by 1 H and 13 C 1 H}-NMR and infrared spectroscopies and showed satisfactory elemental analysis. The X-ray crystallographic studies can be summarised as follows: ( 1 ) triclinic, P -1, a =5.6515(3), b =10.1401(6), c=11.7910(7) A , α =105.4260(10)°, β =94.202(2)° and γ =90.234(2)°, V=649.42(6) A 3 and Z =2; ( 2 ) triclinic, P -1
