Ruthenium(II) carbonyl complexes containing tridentate Schiff bases

New ruthenium(II) complexes, [Ru(CO)(B)(LL′)(PPh3)] (where, LL′ = tridentate Schiff bases; B = PPh3, pyridine, piperidine or morpholine) have been prepared by reacting [RuHCl(CO)(PPh3)3] or [RuHCl(CO)(PPh3)2(B)] with Schiff bases containing donor groups (O, N, X) viz., salicylaldehyde thiosemicarbaz...

Description
Summary:New ruthenium(II) complexes, [Ru(CO)(B)(LL′)(PPh3)] (where, LL′ = tridentate Schiff bases; B = PPh3, pyridine, piperidine or morpholine) have been prepared by reacting [RuHCl(CO)(PPh3)3] or [RuHCl(CO)(PPh3)2(B)] with Schiff bases containing donor groups (O, N, X) viz., salicylaldehyde thiosemicarbazone (X = S), salicylaldehyde semicarbazone (X = O), o-hydroxyacetophenone thiosemicarbazone (X = S) and o-hydroxyacetophenone semicarbazone (X = O). The new complexes were characterised by elemental analysis, spectral (i.r., 1H- and 31P-n.m.r.), data.
