Preparation and characterisation of some new dithiocarbazate schiff base complexes of titanium(IV), tin(IV) and lead(IV)

678-682The dibasic tridentate schiff bases H2SMVD and H2SMND, prepared by the condensation of S-methyldithio-carbazate with 2-hydroxy-3-methpxybenzaldehyd  and 2-hydoxy-l-naphthaldehyde respectively, form neutral penta-coordinated complexes of the type [X2M(schiff base)], (X = Cl, OPri, OBun, Me, Et or Ph) with titanium(IV), tin(IV) and lead(IV) organometallics. The triphenyltin(IV) and triphenyllead(IV) complexes also show evidences for pentacoordination. The complexes are characterised on the basis of IR, 1H NMR and electronic spectral data

Chelated Titanium(IV) & Organotin(IV) Derivatives of Mixed Azines

Molecular addition complexes of organo-titanium(IV), -tin(IV) and -lead(IV) chlorides with dithiocarbazate schiff bases

971-976Reactions of organo-titanium(IV), -tin(IV) and -lead(IV) chlorides with dithiocarbazate schiff bases in 1:1 molar ratio yield to brown solid molecular addition complexes of the type R2MCl2 (Schiff base) and Ph3MCI (schiff base). The structures of these adducts have been assigned based on elemental analyses, IR and 1H NMR data. The former type of complexes have been found to have hexa-coordinated structures with bidentate N-S coordination, whereas the latter type possess penta-coordination with nitrogen coordinated schiff base. The PhSnCl3 (schiff base) adducts have been found to belong to the former class

Ruthenium{II} & rhodiurrul) complexes of 2-hydroxypyridinest

331-332Ruthenium(II) and rhodiumil) precursors namely RuHCl(CO)(PPh3)3], [Ru(CO)2Cl2]n, [RuCl2(PPh3)3] and [RhH(PPh3)4 react with 2-hydroxypyridine (PyOH) and 6-methyl-2-hydroxypyridine (MePyOH) to afford a range of novel mononuclear complexes, namely [RuCl(CO)(PyO)(PPh3)2], [RuH(CO)(PyO)(PPh3)2], [RuCl(CO)(MePyO)(PPh3)2], [RuH(CO)(MePyO)(PPh3)2], [Ru(MePyO)2(PPh3)2], [Ru(CO)2(PyO)2], [Rh(PyO)(PPh3)2] and [Rh(MePyO)(PPh3)2]. In these complexes the oxypyridines are bound in bidentate (N,O-chelate) mode. The complexes have been characterized by analytical, IR and 1H NMR data. Evidences indicate that [RuH/Cl(CO)(PyO/MePyO)(PPh3)2] complexes exist in two geometrical isomeric forms
