Variable-temperature X-ray structure analysis of azobenzenes reveals that the torsional vibration of the N-Ph bonds is large enough to give rise to conformational interconversion in crystals.

Variable-temperature X-ray crystal structure analyses of N-benzylideneanilines revealed that the torsional vibration of the C-Ph and N-Ph bonds causes an apparent shortening of the C=N bond at room temperature.

A new interference technique to measure the transverse coherence of X-ray free-electron lasers is proposed and applied to the characterization of the coherence properties of ultra-intense focused X-ray pulses from the SPring-8 Ångstrom Compact free-electron LAser (SACLA).

In many cases, complexes of platinum and other metals have a symmetrical structure. In contrast, in the platinum(II) complex with pyridine and N-(9-anthracenylmeth­yl)-1,2-ethanedi­amine as ligands, the molecular structure is asymmetric. Only one of the two pyridine rings is π-stacked with the anthracene ligand enhancing the asymmetry.

The title compound, C25H31BF2N2O, is a potential boron tracedrug in boron neutron capture therapy (BNCT), in which the B atom adopts a distorted BN2F2 tetra­hedral geometry: it is soluble in dimethyl sulfoxide, di­methyl­formamide and methanol. The pyrrolyl­idene­methyl­pyrrole triple fused ring system is almost planar (r.m.s. deviation = 0.031 Å) and subtends a dihedral angle of 47.09 (5)° with the plane of the pendant phenol ring. The phenol -OH group is blocked from forming hydrogen bonds by the adjacent bulky tert-butyl groups. In the crystal, inversion dimers linked by pairs of very weak C-H...F inter­actions generate R22(22) loops.
