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.

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.

In the title compound, C21H21O5PS·H2O·CH2Cl2, the phosphonium–sulfonate zwitterion has the acidic H atom located on the P atom rather than the sulfonate group. The S—O bond lengths [1.4453 (15)–1.4521 (14) Å] are essentially equal. In the crystal, the water molecules bridge two zwitterionsviaOwater—H...Osulfonatehydrogen bonds into a centrosymmetric dimer. The dimers are further linked by weak CAryl—H...Osulfonatehydrogen bonds into chains extending along [100]. The PH+group is not involved in intermolecular interactions.

Diphenyl Disulfide

The title compound, C19H17PS2, results from the direct deprotonation of diphenylmethylphosphine sulfide and subsequent reaction with diphenyl disulfide. The C—P and C—S bond lengths of 1.8242 (18) and 1.8009 (18) Å, respectively, of the central P—C—S linkage are comparable to those found in the sulfonyl analogue, but are considerably longer than those reported for the dimetallated sulfonyl compound. The dihedral angle between the benzene rings of the diphenylmethyl moiety is 69.46 (7)°. No distinct intermolecular interactions are present in the crystal structure.

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.
