Laser desorption/ionization (LDI MS) and thermoprogrammed desorption mass spectrometry (TPD MS) of Europium(III) coordination compound with n-{bis[methyl(Phenyl)amino]phosphorYl}-benzenesulfoneamide

Abstract

The coordination compound EuL 3 P h e n ( w h e r e L -= N-{bis[methyl(phenyl)amino]phosphoryl}-benzenesulfoneamidate anion) has been synthesized and studied by laser-desorption and temperatureprogrammed mass spectrometry in the condensed phase and on the surface of a standard metal substrate. The temperature dependence of the main mass spectrum components in the method of temperature-programmed desorption mass spectrometry (TPD MS) is defined and interpreted, components of the laser desorption/ionization (LDI) mass spectrum of the synthesized substance have been identified. A comparative analysis of mass spectra obtained by both methods for the studied coordination compound has been carried out.A possibility of both mass spectrometric methods using for the investigation of metal-containing polymer components is discussed.

“…Two absorption bands from CO group vibrations can be explained by different type of coordination (monodentate or bidentate) [8]. The IR spectra of the sodium salt NaHL and Tb(HL) 2 (NO 3 ) reveal shifts of the characteristic stretching vibrations in comparison with the neutral ligand H 2 L which indicate a significant delocalization of π-electron density in the CONPO fragment (Δυ as (CO) = = 10-30 cm -1 , and Δυ(P=O) = 38-46 cm -1 ) [9,10]. X-ray diffraction study was carried out for Tb(HL) 2 (NO 3 ).…”

“…Experimental values and theoretically calculated mass of the core fragments are presented in Table. The formation of such associates with alkali metals ions is characteristic for various classes of coordination compounds [9,10]. Low ionization capability of the formed fragments leads to low intensity of the respective peaks.…”
