Infrared spectroscopic and thermo gravimetric study of hofmann-type host-guest compounds provided by ligand molecule paraphenylenediamine

In this study, similar to Hofmann-type, formulated as M(PPD)Ni(CN)4.2G (M = Mn, Ni, Cu, Zn, Cd; G = 1,3DiClBz), M(PPD)Ni(CN)4.2G (M = Mn, Co, Zn, Cd; G = 1,4DiClBz) and M(PPD)Ni(CN)4.2G (M = Mn, Ni, Cu, Cd; G = CPN) host-guest compounds have been firstly obtained chemically. The vibrational wave numbers of ligand molecule and Ni(CN)42- ion and guest molecules have been recorded by FTIR spectrometer in the spectroscopic region of (4000-50) cm-1. The thermal behaviors of these compounds have been investigated by Thermal Gravimetric Analysis (TG), Differential Thermal Analysis (DTA) and Differential Thermal Gravimetry (DTG). The results show that these compounds are similar in structure to Hofmann-type compounds and it has been observed that structures consist of polymeric layers |M-Ni(CN)4|? and the paraphenylenediamine molecule has bounded to the metal atom (M).
