Bis(1,10-phenanthroline)copper(II)-μ-cyano-cyano(1,10-phenanthroline)copper(I) thiocyanate dihydrate

By reaction of Cu(NO 3 ) 2 , NH 4 OH, phen (1,10-phenanthroline), KSCN and KCN in the molar ratio 1:40:2:1:1 in a water-ethanol solution a new mixed-valence complex, μ-cyano-1κN:2κC-cyano-2κN-tris(1,10-phenanthroline)-1κ 4 N,N';2k 2 N,N'-dicopper(I,II) thiocyanate dihydrate, [Cu 2 (phen) 3 (CN) 2 ](SCN).2H 2 O, was prepared. The [Cu II (phen) 2 ] 2+ and [Cu(phen)CN] moieties are bridged by a CN - ion giving rise to a binuclear cation with deformed trigonal-bipyramidal and deformed tetrahedral coordination for the divalent and univalent Cu atoms, respectively
