New Hofmann type complexes in the form of M(pp)(2)Ni(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)(2)Ni(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)|(infinity) with the pp molecule bounded to the metal atom (M).
已制备出呈粉末状的新型霍夫曼型配合物M(pp)₂Ni(CN)₄（其中pp = 1 - 苯基哌嗪且M = Ni、Co、Cd、Pd或Mn），并报道了其在(4000 - 400) cm⁻¹范围内的红外光谱。通过差示热分析（DTA）和热重分析（TGA）研究了这些配合物的热行为。已通过透射电子显微镜（TEM）对Ni(pp)₂Ni(CN)₄配合物进行了检测。结果表明，这些化合物在结构上与霍夫曼型配合物相似，其结构由聚合物层|M - Ni(CN)₄|∞组成，其中pp分子与金属原子（M）相连。
