Unexpected Behaviour in Derivatives of Barluenga's Reagent, HalColl2X (Coll = 2,4,6-trimethyl pyridine, collidine; Hal = I, Br; X = PF6, ClO4 & BF4)

Abstract

For the collidine analogues of Barluenga's Reagent (IPy2BF4) reported, a flat cation is necessary for the generation of a modulated phase, in keeping with the ``Ratchet Model'' theory [Kim et al., Crystal Growth & Design, 2014, 14, 6294]. Attempts to study "diffuse modulation" in Br(Coll)2ClO4 have shown that these non-Bragg features disappear very rapidly on exposure to synchrotron radiation, an effect thought to be caused by the radiation damage disrupting the lattice vibrations that cause the modulation.
