Modification of supramolecular motifs: perturbation of the structure of anextended hydrogen-bonded biuret array by interaction with an intercalated copper complex and methanol molecules

The almost planar sheets formed by hydrogen bonding between biuret molecule s become significantly more folded when intercalated bis{di(methoxycarbimid o)amine}copper(II) bromide, methanol and acetonitrile molecules are introdu ced into the lattice; an examination of the crystal structure suggests that selective control of the perturbation of the biuret sheets may be possible through appropriate variation of the intercalating species.
