The first dinuclear nickel complex with an azapurine derivative is reported. The crystal structure consists of discrete [Ni 2 (dmax) 3 (H 2 O) 2 (dben) 2 ] + cations, the charge of which is balanced by interstitial dmax anions, where dmax=4,6-dimethyl-1,2,3-triazolo[4,5-d]pyrimidin-5,7-dionato and dben = N,N′-dibenzylethylenediamine. The nickel centres...
Several Cu(II) complexes with 1,2,4-triazolo[1,5-a]pyrimidine (tp) and its 5,7-dimethyl derivative (dmtp) have been isolated and structurally characterized. Five of them are mononuclear and contain 1,10-phenanthroline (phen) or ethylenediamine (en) as auxiliary ligands, their formula being [Cu(H 2 O)(phen)(tp) 2 ](ClO 4 ) 2 ·H 2 O, [Cu(H 2 O)(phen)(dmtp)...
