The title complex, Cu ( [9]aneN3)C12 (l), behaves anomalously with regard to the well-known macrocyclic effect. Typically, macrocyclic pol amine Cu(I1) complexes exhibit polyamines.2 However, the formation constant of 1 (log K is: 16) is smaller than that of Cu(dien)z+ (log K = 18.0).*g3 larger formation constants yh t an those of corresponding linear dien 19 lane% In contrast, formation constants of Ni( [9]aneN#+ and Zn-([9]a11eN~)~' (log K = 16.2 and 11.6, respectively) are substantially larger than those of Ni(dien)2+ and Zn(dien)" (log K = 10.7 and 8.9, re~pectively).~ The anomalous behavior of 1 has been attributed2" to steric requirements of Cu(I1) which have been frustrated in part by structural constraints of the [9]aneN3 ligand. The present study was undertaken to help understand these constraint^.^ Experimental SectionPreparation of 1. 1,4,7-Triazacyclononane trihydrochloride ( [9]aneN3.3HC1) was prepared by appropriate modification of a published procedure for 1,5,9,13-tetraazacy~lohexadecane.~ Evaporation of a solution of [9]aneN3.3HC1 (5 mmol, 1.24 g), CuC12 (5 mmol, 0.85 g), and 15 mL of 1 N sodium hydroxide yielded sodium chloride crystals and large blue plates of 1 which were separated manually and recrystallized from water to yield pure 1.

“…These ligands on reaction with [RuX 3 (EPh 3 ) 3 ] (X = Cl or Br; E = P or As) [7][8][9] in toluene (1:1 molar ratio) yielded new stable ruthenium(III) complexes of the type [RuX 2 (L)(PPh 3 ) 2 ] or [RuX 2 (L)(AsPh 3 ) 2 ] {where L = N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives, X = Cl or Br} [10]. In all the reactions, the ligands replace one triphenylphosphine/ triphenylarsine and one chloride/bromide ion from starting complexes (Scheme 1).…”

Six different ruthenium(III) complexes of Schiff bases derived from 2-hydroxy-1-naphthaldehyde and o-aminophenol/o-aminothiophenol have been synthesized. The compounds with the general formula [RuX(EPh 3 ) 2 (L)] (X = Cl or Br; E = P or As; L = bifunctional tridentate ONO/ONS donor Schiff base ligand) were characterized by infrared, electronic, electron paramagnetic resonance spectroscopy and elemental analyses. Spectroscopic investigation reveals coordination of Schiff base ligand through ONO/ONS donor atoms and octahedral geometry around ruthenium metal. Redox property of complexes has been examined by using cyclic voltammetry. The catalytic oxidation property of ruthenium(III) complexes were also investigated.
