Solid state multinuclear NMR study of sigma-acetylide complexes of platinum, trans-[ClPt(PnBu3)2-C=C-p-C6H4-C=C-Pt(PnBu3)2Cl] and trans-[-Pt(PnBu3)2-C=C-p-C6H4-C=C-]n.

ABSTRACT

Solid state 13C, 31P and 195Pt NMR has been employed to study the electronic and geometric structure of the dimeric and polymeric sigma-acetylide complexes of platinum, trans-[ClPt(PnBu3)2-C identical to C-p-C6H4-C identical to C-Pt(PnBu3)2Cl] and trans-[-Pt(PnBu3)2-C identical to C-p-C6H4-C identical to C-]n. The 195Pt shielding tensor has been measured and analysed to reveal details about the electronic properties of the Pt-ligand bonds.
