Thermal and spectral properties of di- and trimethoxybenzoates of silver (I)

“…Probably it is connected with the different participations of the inductive and mesomeric effects of methoxygroups in the electron density of the system. In our previously published papers [6,8,[10][11][12] it was said that the complexes of 3,5-dimethoxybenzoates with Co(II), Ni(II) and Cu(II) were more thermally stable than those of the remaining isomers. The hydrates of 3,5-dimethoxybenzoates of Co(II), Ni(II) and Cu(II) losing water molecules in one step form the anhydrous compounds that next are decomposed at higher temperatures than dimethoxy-and trimethoxybenzoates of those elements.…”

“…In our earlier papers the synthesis of complexes of Co(II), Ni(II) and Cu(II) with various isomers of di-and trimethoxybenzoic acid anions was described and the investigation of their properties was presented [3][4][5][6][7][8][9][10][11][12]. Now we decided to present the preparation of di-and trimethoxybenzoates of Ag(I) in the solid state, and the examination of their properties such as: thermal stability in air, solubility in water, the ways of coordination of carboxylate groups and their crystalline form.…”

Magnetic, thermal and spectral characterization of 2,6-dimethoxybenzoates of Co(II), Ni(II) and Cu(II)

“…There are papers that deal with their complexes with d-and mainly 4f metal ion elements [3][4][5][6][7][8][9][10][11][12][13][14][15] The compounds of 2,6-dimethoxybenzoic acid anion with following cations: Cu(II), Mn(II), Co(II), Ni(II), Zn(II) and some of Ln(III) have been obtained in solids or studied in solution [16][17][18].…”

Synthesis, characterization and thermal behaviour of solid-state compounds of 4-methoxybenzoate with some bivalent transition metal ions

“…Several papers reported the thermal stability and thermal decomposition of solid-state salts as thorium with several organic acids, including 4-methoxybenzoic acid [6], as well as benzoic and mhydroxybenzoic acids [7]; the thermal decomposition of nickel benzoate and of the nickel salt of ciclohexane carboxylic acid [8]; the thermal and spectral behaviour on solid compounds of benzoates and its methoxy derivates with rare earth elements [9-12, 14, 15-17] ; the vibrational and electronic spectroscopic study of lanthanides and effect of sodium on the aromatic system of benzoic acid [13,16]; the reaction of bivalent cooper, cobalt and nickel with 3-hidroxy-4-methoxy and 3-methoxy-4-hidroxybenzoic acids and a structure for these compounds has been proposed on the basis of spectroscopic and thermogravimetric data [18]; the thermal decomposition of thorium salts of benzoic and 4-methoxybenzoic acids in air atmosphere [19]; the thermal and spectral behaviour on solid compounds of 5-chloro-2-methoxybenzoate with rare earth and d-block elements [20][21][22][23]; the synthesis and characterization of 2,3-dimethoxybenzoates of heavy lanthanides and yttrium [24]; the spectral and magnetic studies of 2-chloro-5-nitrobenzoates of rare earth elements [25] and thermal behaviour of solid state 4-methoxybenzoates of some bivalent transition metal ions [26].…”
