A new near-IR luminescent erbium(III) complex with potential application in OLE...
Martín-Ramos, Pablo; Miranda, Micael D.; Silva, Manuela Ramos; Eusebio, M. Ermelinda S.; Lavín, Víctor; Martín-Gil, JesúsWe report the synthesis and X-ray structural characterization of the new Er3+ ternary complex [Er(hd)3(bipy)] (where Hhd is 3,5-heptanedione and bipy is 2,2′-bipyridine) as well as its absorption/luminescent properties. X-ray analysis of the novel complex reveals its triclinic centrosymmetric structure with two symmetry independent complexes in the unit cell. Each lanthanide ion is surrounded by 6 oxygen atoms ...
A ladder type structure: Rubidium diphenylacetate diphenylacetic acid
Silva, Manuela; Beja, Ana; Paixão, José A.; Domingos, Sérgio R.; Martín-Gil, JesúsA new rubidium complex, rubidium diphenylacetate diphenylacetic acid has been synthesised and characterised by single-crystal X-ray diffraction: triclinic, P $$\bar1$$ with a=7.437(3) , b=12.377(4) , c=14.384(3) , a=107.08(2), ß=103.67(2), ?=96.95(3), Mr=508.93, V=1203.6(6) 3, Z=2. The diphenylacetic molecules bridge the metallic ions forming an infinite ladder structure. Two strong hydrogen bonds link the orga...
Synthesis, crystal structure and magnetic properties of an alternating manganes...
Silva, Manuela Ramos; Beja, Ana Matos; Paixão, José António; Martín-Gil, JesusA new 1D complex has been prepared and characterized. X-ray single crystal structure confirms that the Mn(II) ions assemble in alternating chains with Mn-Mn distances of 3.8432(13) and 4.4428(14) Å. A 3D network of hydrogen bonds links the chains together. The temperature dependence of the magnetic susceptibility reveals that this compound undergoes a magnetic transition and exhibits an antiferromagnetic intera...
