Bu çalışmada M(p-Fenilendiamin)Ni(CN)4.2G (M = Co, Zn, Cd ve G = 1,4-Diklorobenzen) klatratları ilk kez ve toz olarak elde edildi. Bu klatratların infrared spektrumları (4000 – 400) cm-1 spektroskopik bölgesinde alındı ve soğurma titreşim modları işaretlendi. Bu işaretlemeler bilimsel kaynaklarda yer alan diğer Hofmann-tipi klatratların işaretlemeleri ile karşılaştırıldı ve benzer sonuçlar gözlendi. Bu klatratların termal davranışları, termogravimetrik analiz (TG), diferansiyel termal analiz (DTA) ve diferansiyel termogravimetrik analiz (DTG) yöntemleri ile incelendi. Bu çalışma sonucunda Hofmann-tipi klatratlara üç yeni örnek katılmıştır.

THE SYNTHESIS OF M(p-PHENYLENEDIAMINE)Ni(CN)4.2G (M = Co, Zn, Cd and G = 1,4- DICHLOROBENZENE) HOFMANN TYPE CLATHRATES and INVESTIGATION OF THEIR STRUCTURAL PROPERTIES

Öz

In this study, clathrates of M(p-Phenylenediamine)Ni(CN)4.2G (M = Co, Zn, Cd and G = 1,4-Dichlorobenzene) were obtained in powder form for the first time. The infrared spectra of these clathrates were taken in (4000 - 400) cm-1 spectroscopic range and the absorption vibration modes were assigned. These assignments were compared with those of other Hofmann-type clathrates in the literature and similar results were observed. The thermal behaviors of these clathrates were studied by thermogravimetric analysis (TG), differential thermal analysis (DTA) and differential thermogravimetric analysis (DTG) methods. As a result of this study, three new examples were added to Hofmann-type clathrates.
