THE SYNTHESIS, STRUCTURE, AND BONDING IN SOME LANTHANIDE(III) COORDINATION COMPOUNDS OF 4-[(N-FURFURAL)AMINO]ANTIPYRINE
摘要:
Some seven-, eight-, nine- and ten-coordinated complexes of lanthanide(III) with 4-[(N-furfural)amino]antipyrine (FFAP) were prepared in ethanol or methanol as solvent. The complexes have the general composition LnX(3).nFFAP (Ln = La, Pr, Nd, Sm, Gd? Tb or Dy; X = NO3- n = 2; X = NCS-, n = 2 or 3; X = ClO4-, n = 4). The structure and bonding of these compounds of high coordination number were established with the help of chemical analyses, conductance, molecular weights, magnetic measurements, IR and electronic spectral data. The thermal stabilities of these compounds were also studied by TGA.
