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

The almost planar sheets formed by hydrogen bonding between biuret molecules become significantly more folded when intercalated bis{di(methoxycarbimido)amine}copper(II) bromide, methanol and acetonitrile molecules are introduced 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.
