A series of ruthenium(II) mixed ligand complexes of the type [Ru(NH(3))(4)(L)](2+), where L=imidazo[4,5-f][1,10]phenanthroline (ip), 2-phenylimidazo[4,5-f][1,10]phenanthroline (pip), 2-(2-hydroxyphenyl)imidazo[4,5-f][1,10]phenanthroline (hpip), 4,7-diphenyl-1,10-phenanthroline (dip), naphtha[2,3-a]dipyrido[3,2-h:2',3'-f]phenazine-5,18-dione (qdppz),(More)
The coordination geometry around copper(II) in [Cu(imda)(phen)(H2O)] (1) (H2imda = iminodiacetic acid, phen = 1,10-phenanthroline) is described as distorted octahedral while those in [Cu(imda)(5,6-dmp)] (2) (5,6-dmp = 5,6-dimethyl-1,10-phenanthroline) and [Cu(imda)(dpq)] (3) (dpq = dipyrido-[3,2-d:2',3'-f]-quinoxaline) as trigonal bipyramidal distorted(More)
Copper(II) complexes of three linear unsymmetrical tridentate ligands viz. N-methyl-N'-(pyrid-2-ylmethyl)ethylenediamine (L1), N,N-dimethyl-N'-(pyrid-2-ylmethyl)ethylenediamine (L2) and N,N-dimethyl-N'-((6-methyl)pyrid-2-ylmethyl)ethylenediamine (L3) have been isolated and characterized by elemental analysis, electronic absorption and EPR spectroscopy and(More)
