abstract = {Halogen bonding enables the mechanochemical ball-milling
isomerization of an otherwise persistent cis-coordinated
metal complex into the corresponding trans-isomer. The
importance of halogen bonding for enabling the cis→trans
isomerization of the metal centre is evidenced by real-time
in situ synchrotron powder X-ray diffraction monitoring of
the ball-milling experiments that showed the transient
appearance of a cis-geometry metal-organic halogen-bonded
(MOXB) cocrystal, which is rapidly replaced by the
corresponding trans-geometry one, with any excess,
non-halogen-bonded cis-geometry complex being retained
throughout the milling experiment. The importance of
cocrystallization for cis→trans isomerization is supported
by periodic density-functional theory calculations which
show that the process becomes notably more enthalpically
favourable in the presence of the halogen bond donor. The
presented work indicates that the formation of MOXB
cocrystals can open the door to new, metal-based responsive
behaviours, different from those of parent solid-state
coordination complexes.},
