Abstract

İ ki boyutlu kordinasyon polimer kompleksleri M AMPM 2Ni CN 4 burada M= Mn, Co, Ni ve Cd; AMPM= 2-amino4-metilpirimidin ilk kez elde edilmiş ve FT-IR, FT-Raman ve far-IR spektroskopi ile incelenmiştir. Ayrıca bu komplekslerin, termal gravimetrik analizi TGA , taramalı termal analizi DTA , X-ray saçılması ve elemental analiz ölçümleri yapıldı. AMPM molekülleri pirimidin halkasının azot atomlarının biri ile kordinasyon yaptığı bulunmuştur. Ni CN 42- iyonları ile M AMPM 22+ katyonlarının koordinasyonu sonucu, Hofmann tipi iki boyutlu kordinasyon polimer bileşikleri oluşturduğu spektral özellikler ile desteklenmiştir. AMPM ve Ni CN grubunun her ikisinden kaynaklanan titreşim bandları tanımlanmıştır

Vibrational Spectroscopic Investigation of 2-amino-4-methylpyrimidine Tetracyanonickelate Complexes

Abstract

New Hofmann-type complexes in the form of M AMPM 2Ni CN 4 where M = Mn, Co, Ni or Cd; AMPM= 2-amino-4-methylpyrimidine were prepared in powder form and their FT-IR, far-IR, FT-Raman spectra are reported. The complexes are also characterized by thermal gravimetric analysis TGA , differential thermal analysis DTA , X-ray diffraction XRD and elemental analyses measurements. AMPM molecules are found to involve coordination through one of the pyrimidine ring nitrogen atoms. The spectral features suggest that the compounds are similar in structure to the Hofmann type two dimensional coordination polymer compounds, formed with Ni CN 42- ions bridged by M AMPM 2 2+ cations. Vibrational bands originated from both AMPM and Ni CN 4 group were assigned.
