The title compound, Rb2O2·2NH3, has been obtained as a reaction product of rubidium metal dissolved in liquid ammonia and glucuronic acid. As a result of the low-temperature crystallization, a disolvate was formed. To our knowledge, only one other solvate of an alkali metal peroxide is known: Na2O2·8H2O has been reported by Grehlet al.[Acta Cryst.(1995), C51, 1038–1040]. We determined the peroxide bond length to be 1.530 (11) Å, which is in accordance with the length reported by Bremm & Jansen [Z. Anorg. Allg. Chem.(1992),610, 64–66]. One of the ammonia solvate molecules is disordered relative to a mirror plane, with 0.5 occupancy for the corresponding nitrogen atom.

Single crystals of the title compound, [Al(iBu)2(O2CCPh3)]2 or [Al2(C4H9)4(C20H15O2)2], have been formed in the reaction between tris(tetrahydrofuran)tris(triphenylacetato)neodymium, [Nd(Ph3CCOO)3(THF)3], and triisobutylaluminium, Al(iBu)3, in hexane followed by low-temperature crystallization (243 K) from the reaction mixture. The structure has triclinic (P\overline{1}) symmetry at 120 K. The dimeric complex [Al(iBu)2(O2CCPh3-μ-κO:κO′)]2 is located about an inversion centre. The triphenylacetate ligand displays a μ-κO:κO′-bridging coordination mode, leading to the formation of an octagonal Al2O4C2 core. The complex displays HPh...CPh intermolecular interactions.

ABSTRACTStoichiometric and Ti-doped LiNbO3 films could be synthesized by the organometallic route. The films were epitaxially crystallized at temperatures around 400°C on sapphire substrates. The reaction control of alkoxides in solvent was found to be very critical for adjusting the stoichiometry and the low temperature crystallization, as well as the crystallization in water vapor stream.
