Copper(II)/di-2-pyridyl ketone chemistry: A triangular cluster displaying antisymmetric exchange versus an 1D coordination polymer

A triangular non-oxo centered cluster and an 1D coordination polymer have been prepared from a reaction “blend” containing Cu(ClO4)2·6H2O and di-2-pyridyl ketone, (py)2CO. A model involving antisymmetric exchange has been used to interpret the magnetic data of the copper(II) triangle.
