THE INVESTIGATION OF HOFMANN TYPE COMPLEXES OF M(O-AMINOTHIOPHENOL)NI(CN)4 (M = CD AND HG) BY FT-IR SPECTROSCOPY

Öz

In this study, Hofmann Type complexes of o-Aminothiophenol–tetracyanonickel, given by the general formula M(o-Aminothiophenol)Ni(CN)₄ (M = Cd and Hg), is obtained for the first time through chemical methods. The FT-IR spectroscopic data in the region of (4000–400) cm^-1 was recorded and the IR frequencies were given and explained in detail. The spectral analyses, results of the newly synthesized complex of o–Aminothiophenol tetracyanonickel suggest that these complexes are new examples of the Hofmann–type complex. In our study, the Hofmann-type complex formed by bounding electrons of sulfur and nitrogen atoms of o–Aminothiophenol (2ATP) ligand molecule to transition metal atoms consist of the corrugated |M–Ni(CN)₄|_∞ polymeric layers which are held in parallel through the chain of (–M–2ATP–M–).

HOFMANN TİPİ M(O-AMİNOTİYOFENOL)Nİ(CN)4 (M = CD VE HG) KOMPLEKSLERİNİN FT-IR SPEKTROSKOPİSİ İLE İNCELENMESİ

Öz

Bu çalışmada, genel formülü M(o-Aminotiyofenol)Ni(CN)₄ (M = Cd ve Hg) olan Hofmann-tipi kompleksler kimyasal yollardan ilk kez elde edildi.  Elde edilen komplekslerin infrared spektrumları (4000–400) cm^-1 spektroskopik bölgesinde alınarak soğurma titreşim modları belirlendi ve onların tanımlamaları yapıldı. Bu sonuçlar literatürde yer alan diğer Hofmann-tipi komplekslerle karşılaştırıldı ve benzer sonuçlar gözlendi. Bu çalışmamızdaki Hofmann tipi komplekslerin o-Aminotiyofenol (2ATP) ligand molekülünün kükürt ve azot atomları üzerinden geçiş metali atomlarına bağlanmasıyla oluştuğu ve |M–Ni(CN)₄|_¥  polimerik tabakalarının ise (–M–2ATP–M–) zincirleri tarafından paralel halde tutulduğu düşünülmektedir.  Bu çalışma sonucunda Hofmann-tipi komplekslere iki yeni örnek kazandırılmıştır.
