Birinci Sıra Geçiş Metali İyonlarını İçeren ONO, ONNO ve O3N3 Tipi Schiff Bazı Komplekslerinin Elektron İyonlaştırma Kütle Spektrumları

Abstract

Bis-N,N'(salisiliden)-1,3-diaminopropan (LH2), Bis-N,N'(salisiliden)-2,2'-dimetil-1,3-diaminopropan (LDMH2), N(salisiliden)-2-hidroksianilin (SAP) ve Tris-N,N',N''(salisiliden)-2,2',2''-aminoetilamin (Trensal) ile tek, iki ve üç çekirdekli Fe(III), Co(II), Ni(II) ve Cu(II) kompleksleri hazırlanmış ve direkt inlet (DI) giriş sisteminde 30-110 eV enerjili elektronlarla iyonlaştırılmıştır. Metal-oksijen kovalent bağı içeren bileşiklerde moleküler pik gözlenirken koordinatif bağ içeren çok çekirdekli komplekslerde bu pikler görülmemiştir. Koordinatif bağların elektron etkisi (EI) ile parçalandığı sonucuna varılmıştır. Termogravimetrik analiz, 300 °C'ye kadar kararlı olan tek çekirdekli kompleksler için gözlenen moleküler pikin ayrıca temel pik olduğunu da ortaya koymaktadır. Bu sıcaklıklarda parçalanan iki ve üç çekirdekli kompleksler için elde edilen pikler, moleküler sinyal olarak gözlenememiştir. Elde edilen fragmentler değerlendirilerek literatür verileri ile karşılaştırılmıştır.

The Electron Ionization Mass Spectra of ONO, ONNO and O3N3 Type Schiff Base Complexes Containing First Row Transition Metal Ions

Abstract

Mono-, di- and trinuclear complexes of Fe(III), Co(II), Ni(II), and Cu(II) ions with Bis-N,N'(salicylidene)-1,3-diaminopropane (LH2), Bis-N,N'(salicylidene)-2,2'-dimethyl-1,3-diaminopropane (LDMH2), N(salicylidene)-2-hydroxyaniline (SAP), and Tris-N,N',N''(salicylidene)-2,2',2''-aminoethylamine (Trensal) were prepared and ionized with 30-110 eV electrons in direct inlet (DI). Compounds with metal-oxygen covalent bonds were observed to give molecular peaks, whereas polynuclear complexes containing coordinative bonds did not have such peaks. It was concluded that the coordinative bonds were dissociated by electron impact (EI). The thermogravimetric analysis reveals that the molecular peak observed for the mononuclear complexes which are stable up to 300 °C is also the base peak. The peaks obtained for the di- and trinuclear complexes that decomposed at these temperatures could not be observed as a molecular signal. The resulting fragments were evaluated and compared with the literature data.
