A self-assembled helix from 4,6-dimethylpyrimidine and copper(II) bromide
A 1:1 polymeric complex of 4,6-dimethlpyrimidine and CuBr2 was spontaneously resolved to afford a 61 helix. Steric effects seem to play an important role for constructing a helical structure. Magnetic measurements showed a uniform S = 1/2 1-D behavior. A dinuclear complex is also obtained as a precursor to the polymeric complex.
