Abstract
A project related to the crystal engineering of hydrogen-bonded coordination complexes has been initiatied and some of our first results are presented here. The compounds [Mn(DMU)(6)](ClO4)(2) (1), [Ni(DMU)(6)](ClO4)(2) (2), [Cu(OClO3)(2)(DMU)(4)] (3) and [Zn(DMU)(6)](ClO4)(2) (4) have all been prepared from the reaction of N, N'-dimethylurea (DMU) and the appropriate hydrated metal perchlorate salt. Crystal structure determinations of the four compounds demonstrate the existence of [M(DMU)(6)](2+) cations and ClO4- counterions in (1), (2) and (4), whereas in (3) monodentate coordination of the perchlorate groups leads to molecules. The [ M( DMU)(6)](2+) cations and ClO4- anions self-assemble to form a hydrogen-bonded one-dimensional (1D) architecture in (1) and different 2D hydrogen-bonded networks in (2) and (4). The hydrogen bonding functionalities on the molecules of (3) create a 2D structure. The complexes were also characterised by room-temperature effective magnetic moments and i.r. studies. The data are discussed in terms of the nature of bonding and the known structures.
