M(4-Pridinkarboksialdehid)Ni(CN)4.nG Hofmann Tipi Konak-Konuk Bileşiklerinin Kırmızıaltı Spektroskopik Özelliklerinin İncelenmesi (M = Ni, Cd ve G = 1,4-Dioksan)

Abstract

Bu çalışmada ilk kez toz şeklinde elde edilen M(4-Pridinkarboksialdehid)Ni(CN)4.nG (M = Ni, Cd ve G = 1,4-dioksan) klatratlarının kırmızıaltı spektrumları (3000–400) cm-1 spektroskopik bölgesinde alınarak soğurma titreşim modları ve onların tanımlamaları yapıldı. Bu tanımlamalar literatürde yer alan diğer Hofmann-tipi klatratlar ile karşılaştırıldı ve benzer sonuçlar gözlendi. Bu çalışmamızdaki Hofmann tipi dioksan klatratları 4- pridinkarboksialdehid ligand molekülünün piridin halkası üzerindeki azot atomu ve aldehit (-CH=O) grubunun oksijen atomunun geçiş metali atomlarına bağlanmasıyla oluştuğu ve |M–Ni(CN)4| polimerik tabakalarının ise (–M–4PCA–M–) zincirleri tarafından paralel halde tutulduğu anlaşılmıştır. Bu çalışma sonucunda Hofmann-tipi klatratlara iki yeni örnek kazandırılmıştır.

Investigation of the FT-IR Spectroscopic Properties of M(4-Pyridinecarboxaldehyde)Ni(CN)4.nG Hofmann Type Clathrates (M = Ni, Cd and G = 1,4-Dioxane)

Abstract

In this study, clathrate of 4-pyridinecarboxaldehyde tetracyanonickel-dioxane, given by the formula M(4-Pyridinecarboxaldehyde)Ni(CN)4 nG (m = Ni, Cd and G = 1,4-dioxane), is obtained for the first time through chemical methods. The FT-IR spectroscopic data in the region of (3000–400) cm-1 was recorded and the IR vibrational modes frequencies were given and explained in detail. The spectral analyzes results of the newly synthesized clathrate of 4-pyridinecarboxaldehyde tetracyanonickel- dioxane suggests that these clathrates are new examples of the Hofmann-type dioxane clathrates. In our study, the Hofmann-type dioxane clathrates formed by bounding electrons of nitrogen-donor atom of pyridine ring and electrons of oxygen-donor atom of aldehyde group (-CH=O) of 4-pyridinecarboxaldehyde 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–4PCA–M–)
