Triphenylsilanes are versatile propeller-shaped building blocks and have been used for the syntheses of several novel poly-Lewis-acids. The first solid-state structure of a bisma-silatriptycene as well as investigations in host–guest chemistry of a triple alane with a threefold amine are reported.

Solid State Structure

Reactions of the organometallic phosphinimine Ph3P=N-SiMe3 (1), with aqueous ReO4- and 188ReO4- yield the ion pairs Ph3P=NH2+MO4- (M=Re (2); 188Re (4)). The ion pairs undergo dehydration upon heating to produce the neutral Re(VII) species: Ph3P=N-MO3 (M=Re (3); 188Re (5)). The solid state structure of Ph3P=NH2+ReO4- (2) shows the presence of hydrogen bonding between the iminato hydrogen and the rhenium oxo center. The relevance of such reactions for the design of new radiopharmaceuticals is discussed

The paper describes the solid state structure of a compound of composition [Cu(bipy)3][Cu(bipy)(ala) (ClO4)2]ClO4, in which both the cation and anion are octahedral complex species with copper(II) as coordination center. The cation contains three chelate rings formed by bipy; the anion contains in the quatorial plane a CuONC2 chelate ring formed by the alaninato ligand and a CuN2C2 chelate ring formed by bipy, with two monodentate perchorato ligands in axial positions completing the six-coordination. In the crystal p-p stackings lead to a supramolecular self-assembled structure.

Abstract The reaction of potassium with hexamethyldi-stannane in a refluxing solvent mixture of toluene and tetrahydrofuran (ratio 10:1) yields the red tetrahydrofuran adduct of benzyl potassium (thf)[KCH2C6H5]2 due to the metalation of toluene by the potassium trimethylstannanide intermediate. The solid state structure of (thf)[KCH2C6H5]2 contains dimers with only one potassium coordinated to a tetrahydrofuran molecule. These dimers form a polymer through benzyl bridging with shortest K-C distances at 292 pm.
