| Abstract: | A series of complexes containing Cu(N-N)2Cl2 (N-N=bis(pyrazol-1-yl)methane (bpzm), bis(3,5dimethylpyrazol-1-yl)methane (bdmpzm), 2,2-dipyridylamine (dpa), 5,6-diphenyl-3-(2-pyridyl)-1,2,4-trazine (dppt) and 2,2′-bipyridine (bipy)), Cu(N-N-N)Cl2 (N-N-N=2,2′:6′,2″-terpyridine (terpy)) and HgCl2 building blocks have been synthesized and structurally characterized. Increase in structural dimensionality is observed for [Cu(bpzm)2][HgCl4], [Cu(dpa)2][HgCl3]2 and [Cu(terpy)(μ-Cl)HgCl3] compounds. No coordination polymers have formed in the case of bis(3,5dimethylpyrazol-1-yl)methane, 5,6-diphenyl-3-(2-pyridyl)-1,2,4-trazine and 2,2′-bipyridine. The [Cu(bpzm)2][HgCl4] and [Cu(terpy)(μ-Cl)HgCl3] complexes have been studied by magnetic measurements. |
