Abstract
New Hofmann type complexes in the form of M(pp) 2Ni(CN) 4 (where pp = 1-phenylpiperazine and M = Ni, Co, Cd, Pd or Mn) have been prepared in powder form and their infrared spectra have been reported in the range of (4000–400) cm −1. The thermal behaviours of these complexes have been investigated by differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA). Ni(pp) 2Ni(CN) 4 complex has been examined via transmission electron microscope (TEM). The results suggest that these compounds are similar in structure to Hofmann type complexes and their structures consist of polymeric layers |M–Ni(CN) 4| ∞ with the pp molecule bounded to the metal atom (M).
