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 asymmetric unit of the title salt, C7H7N2+·BF4−, comprises two independent but nearly identical formula units. The solid-state structure comprises corrugated layers of cations and anions, formed by C—H...F hydrogen bonding, that are approximately parallel to (010). Further C—H...F hydrogen bonding consolidates the three-dimensional architecture. The sample was refined as a two-component non-merohedral twin.

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.

Pyridinium Perchlorate

The asymmetric unit of the title salt, C7H7N2+·ClO4−, comprises two independent formula units. The solid-state structure comprises corrugated layers of cations and of anions, approximately parallel to (010). The supramolecular layers are stabilized and connected by C—H...O hydrogen bonding to consolidate a three-dimensional architecture. A close pyridinium–perchlorate N...O contact [2.867 (5) Å] is noted. The crystal was refined as an inversion twin.
