Synthesis, characterization and thermal behaviour of solid-state compounds of 4-methoxybenzoate with lanthanum (III) and trivalent lighter lanthanides

“…In the solid state the papers reported the thermal stability and thermal decomposition of thorium salts with several organic acids, including 4-methoxybenzoic acid [6], as well as benzoic and m-hydroxybenzoic 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][10][11][12][13][14][15][16]; the vibrational and electronic spectroscopic study of lanthanides and effect of sodium on the aromatic system of benzoic acid [17,18]; 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 [19]; the thermal decomposition of thorium salts of benzoic and 4-methoxybenzoic acids in air atmosphere [20]; the thermal and spectral behaviour on solid compounds of 5-chloro-2-methoxybenzoate with rare earth and d-block elements [21][22][23][24]; the synthesis and characterization of 2,3-dimethoxyben-zoates of heavy lanthanides and yttrium [25]; the thermal studies on solid compounds of phenyl substituted derivates of benzyllidenepyruvates with several metal ions [26,27]; the spectral and magnetic studies of 2-chloro-5-nitrobenzoates of rare earth elements [28] and thermal behaviour of solid state 4-methoxybenzoates of some bivalent transition metal ions [29].…”

Thermal decomposition of solid state compounds of lanthanide and yttrium benzoates in CO2 atmosphere

“…A survey of literature shows that the complexes of rare earth elements with benzoic acid and some of their derivatives have been investigated in aqueous solutions [1][2][3][4][5] and in solid state [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

Crystal structures of 5-chloro-2-methoxybenzoates of Mn(II), Co(II), Ni(II) and Zn(II)

“…The ligands form the weak electrostatic field in the coordination sphere of the central ions. The Zn(II) complex is diamagnetic as may be expected from Zn(II) closed shell electronic configuration and the absence of unpaired electrons [2][3][4][5].…”
