Synthesis, characterisation and luminescent properties of lanthanide-organic po...
Girginova, Penka I.; Paz, Filipe A. Almeida; Soares-Santos, Paula C. R.; Ferreira, R. A. Sá; Carlos, Luís D.; Amaral, Vítor S.; Klinowski, JacekThree new lanthanide(III) complexes (Ln = Sm, Tb and Eu) of picolinic and glutaric acid were prepared and characterised. The crystal structure of the complex [Sm(glu)(pic)- (H2O)2] (where Hpic and H2glu stand for picolinic and glutaric acid, respectively) was determined by single-crystal Xray diffraction. All the Ln complexes were characterised by elemental analysis, infrared spectroscopy, X-ray powder diffract...
Synthesis, structure and magnetic behaviour of mixed metal leucophosphite
Shi, Fa-Nian; Santos, António Moreira dos; Cunha-Silva, Luís; Costa, Benilde F.O.; Klinowski, Jacek; Paz, Filipe A. Almeida; Amaral, Vítor S.A synthetic analogue of leucophosphite, an iron phosphate, was synthesized hydrothermally at 180 °C and its chemical composition determined to be K[(FeV)(PO4)2(OH)(H2O)]·H2O. The compound crystallizes in the monoclinic P21/c space group, with a=9.7210(19) Å, b=9.6500(19) Å, c=12.198(4) Å and [beta]=128.569(18)°. While the original all-iron compound is reported to be antiferromagnetic, the inclusion of substitut...
