Synthesis and Crystal Structure of the Europium(II) Hydride Oxide Iodide Eu(5)H(2)O(2)I(4) Showing Blue-Green Luminescence
As the first europium(II) hydride oxide iodide, dark red single crystals of Eu(5)H(2)O(2)I(4) could be synthesized from oxygen-contaminated mixtures of EuH(2) and EuI(2). Its orthorhombic crystal structure (a = 1636.97(9) pm, b = 1369.54(8) pm, c = 604.36(4) pm, Z = 4) was determined via single-crys...

description | As the first europium(II) hydride oxide iodide, dark red single crystals of Eu(5)H(2)O(2)I(4) could be synthesized from oxygen-contaminated mixtures of EuH(2) and EuI(2). Its orthorhombic crystal structure (a = 1636.97(9) pm, b = 1369.54(8) pm, c = 604.36(4) pm, Z = 4) was determined via single-crystal X-ray diffraction in the space group Cmcm. Anion-centred tetrahedra [HEu(4)](7+) and [OEu(4)](6+) serve as central building blocks interconnected via common edges to infinite ribbons parallel to the c axis. These ribbons consist of four trans-edge connected (Eu(2+))(4) tetrahedra as repetition unit, two H(−)-centred ones in the inner part, and two O(2−)-centred ones representing the outer sides. They are positively charged, according to [Formula: see text] {[Eu(5)H(2)O(2)](4+)}, to become interconnected and charge-balanced by iodide anions. Upon excitation with UV light, the compound shows blue–green luminescence with the shortest Eu(2+) emission wavelength ever observed for a hydride derivative, peaking at 463 nm. The magnetic susceptibility of Eu(5)H(2)O(2)I(4) follows the Curie-Weiss law down to 100 K, and exhibits a ferromagnetic ordering transition at about 10 K. |
