Synthesis of Some Bis(triphenylphosphine)(ethynylferrocenyl) Platinum(ii) Complexes - Molecular-structure of [pth(c-equivalent-to-c-c5h4fec5h5)(pph3)2]

Substituted acetylidoplatinum(II) complexes trans-[PtX(C=C-C5H4FeC5H5)(PPh3)2] (X = H, Cl, C=CPh or C=C-C5H4FeC5H5) have been prepared. Controlled basicity of the reaction solutions yields the different complexes. A single-crystal X-ray diffraction study of trans-[PtH(C=C-C5H4FeC5H5)(PPh3)2] indicates an alternating alignment of the ethynyl ligands between two centrosymmetric platinum atoms, resulting in the formation of a pseudo-polymeric-structure.
