Abstract: | Summary Schiff bases (HL) produced by the condensation ofN-methyl-S-methyldithiocarbazate with -diketones and aromatic aldehydes or ketones react with [RuHClCO(PPh3)3] to yield hexacoordinated complexes of the type [RuClCO(PPh3)2(L)]. These Schiff bases react with [RuCl2{P(OR)3}4] in 11 molar ratio to yield [RuCl{P(OR)3}2(L)] in which L is a tridentate. The chlorine atom in the complex can be removed in coordinating solvents in the presence of anions such as [BPh4]– to give cationic complexes. Bis chelate complexes, [Ru{P(OR)3}2(L)2] are prepared from 12 molar proportions of the reactants. These complexes were characterised by elemental analyses, i.r.,1H n.m.r., u.v. and conductivity studies.NCL Communication No. 4224. |
