The October outside cover, designed by Marcus Herlitschke (Jülich Centre for Neutron Science, Germany) et al., presents their paper in which the first experimental results concerning unusual magnetic properties of FeNCN are reported.
This study reveals the unconventional behaviour of the magnetic parameters below the Néel temperature of 350 K. The comparison of the obtained data with literature data of iron monoxide reveals very similar iron phonon modes with a small softening and a slightly reduced sound velocity. The authors showed that iron monoxide and iron carbodiimide exhibit a similar local iron environment with a mean nearest neighbour distance of about 2.2 Å in an octahedral coordination by oxygen or nitrogen, respectively.
The authors also presented measurements of FeNCN, featuring similarities and differences to the related iron monoxide. In summary, the iron carbodiimide is a particularly attractive target for magnetic investigations using Mössbauer spectroscopy and magnetometry.

The inside cover illustrates a paper written by Karl Wallace (University of Southern Mississippi, USA) and his colleagues who are interested in the design of new molecular probes.
The authors have synthesized two coumarin-enamine chemodosimeters which can selectively detect the cyanide ion and investigated the spectroscopic properties in various organic solvents.
