The magnetic measurements of polymeric complexes [L·Cu(hfac)2]n, (L = pyrimidine, 4-methylpyrimdine, and quinazpline) revealed the presence of ferromagnetic interactions among the copper spins. The X-ray crystal-structure analysis of the pyrimidine and quinazoline complexes showed a copper-ligand alternating chain. The ferromagnetic transition of the quinazoline complex was observed at about 0.12 K. Pyrimidine2-Cu(ClO4)2 complex was found to be a ferromagnet with a transition temperature of about 10 K.
