      Abstract:

      The reaction of CuCl with the neutral guanidine Hhpp ligand   (1,3,4,6,7,8-hexahydropyrimido[1,2-a]pyrimidine) yields two   cryst. polymorphs of the neutral dimer,   bis(1,3,4,6,7,8-hexahydropyrimido[1,2-a]pyrimidine)dichloro-di-copper(I),   which were characterized by x-ray crystallog. and 1H NMR and   Raman spectroscopy.  They have the shortest distance known   for a bridging unsupported copper(I)-copper(I) interaction.
