Understanding the packing in the 1 : 1 molecular complex 1,3,5-tricyanobenzene–hexamethylbenzene by probing lattice modes

Abstract

The nature of hydrogen bonding and methyl group dynamics in the 1 : 1 molecular complex of hexamethylbenzene (HMB) and 1,3,5-tricyanobenzene (TCB) was probed using incoherent inelastic neutron scattering. The use of deuterated HMB allowed for the direct comparison of the methyl dynamics in the pure and complexed HMB molecules as well as directly observing changes to the hydrogen bonding about the TCB molecules.
