Nouveaux composés hybrides à base de polycarboxylate

Abstract

This thesis focuses on the synthesis and the structural characterization by single-crystal and powder X-ray diffraction, by different spectroscopic methods, as well as by thermal analyzes and photoluminescence proprieties. These investigations on this type of compound led to the preparation of three coordination polymers based on strontium and the ligand pyromellitate: [Sr(H2BTEC)(H2O)5] (1) [Sr(H2BTEC)(H2O)] (2) [Sr2(BTEC)(H2O)]n (3) Three hybrid compounds based on magnesium and the pyromellitate ligand and the piperazine co-ligand: [Mg (H2O)6] (H2BTEC) (4) [Mg2(BTEC)2(H2O)4].(C4H12N2)2 (5) (C4H12N2) [Mg (H2O)6] (BTEC). 3(H2O) (6)
