Thermogravimetrische Untersuchung von Seltenerdbromid—Tetrahydrofuran-Verbindungen

Cation size dependent reactivity of lanthanide trihalides with bulky alkylcyclopentadienyl anions

“…Mass spectra were taken on a Finnigan MAT 90 mass spectrometer and elemental analyses were performed with Perkin Elmer Elemental Analyzer 240. Tri-tert-butylcyclopentadiene, 67,68 sodium tetraisopropylcyclopentadienide, 41 [CeCl 3 (THF) 1.5 ], 69 [SmCl 3 (THF) 2 ], 69 [Cp 0 2 Sm], 26 LnI 3 (Ln = La and Tm) 70 and YbI 2 71 were prepared as previously reported. Anhydrous trichlorides of praseodymium, neodymium, thulium, ytterbium, and lutetium were purchased from Strem Chemicals and used as received.…”

Structure and Thermal Properties of Lithium Cyanate

“…Reckeweg et al1 published a new structure solution of sodium cyanate with approximately the same distances and values of angels and lattice parameters. In this work the structure of lithium cyanate was solved and some physico‐chemical characteristics of lithium cyanate are reported, which was not known in the literature9,11 before.…”

“…Only few complex compounds are mentioned 6–8. The missing compound in the series of the alkaline metal cyanates, LiOCN, was first synthesized in 1966 by Rossmanith et al9 Because of a lack of single crystals (flat intergrown blankets), a crystal structure determination was not possible until now. Similar problems were already discussed for the structure solution of sodium cyanate 10.…”
