Mixed-ligand organometallic derivatives of palladium (O), platinum (O) rhodium (1) and iridium (1) with triphenyl phosphine and 1-benzyl-tetrazoline-5-thione
نویسندگان
چکیده
Four coordinate tetrahedral (Pd0 and Pt0) and square planar (Rh+ and Ir+) complexes of triphenyl phosphine and 1-benzyl tetrazoline-5-thione have been prepared and characterised on the basis of elemental analysis and spectroscopic data (IR, UV-vis, 1HNMR). Bonding of tetrazole ligand occurs through thione tautometric form. Determination of oxidation state of central metal atom in the complexes is verified by idometric and acidimetric titration.

Organometallic derivatives of palladium (o) with 1-substituted tetrazoline-5- thione
Oraganometallic derivatives of palladium (o) have been isolated from the displacement reaction of Pd(Pφ3)4 with 1–substituted tetrazoline-5-thione with phenyl, orthotolyl, paratolyl, parachlorophenyl and benzoyl substitution in benzene medium. Most probable tetrahedral structure is assigned on the basic of elemental analysis, electronic, infrared, far infrared and 1H NMR spectral studies.

Chloride abstraction, using AgPF6, from tri(1cyclohepta-2,4,6-trienyl)phosphane platinum and palladium dichloride, [P]MCl2 [M = Pt (1), Pd (2)], affords the complexes {[P]MCl}PF6 [M = Pt (3), Pd (4)] in good yields. The central metal is coordinated by the chloro ligand, the phosphorus atom and by three η2-C=C units, one of each C7H7 ring. This assignment of a highly symmetrical C3v structure is...

In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)], the coordination geometry of the Rh(I) atom is square-planar, formed by the coordinating N and O atoms of the bidentate enaminoketonate ligand, one C atom from the carbonyl group and a P atom from triphenyl-phosphine. The complex displays a 0.591 (3):0.409 (3) ratio disorder of the phenyl unit of the monoanionic N,O-bidentate ligand. I...
