Organophosphines in PtPCOX (X = N, Cl, S), PtPCNX (X = Cl, S, Br, I, As) and PtPCClX (X = S, I, As) derivatives: structural aspects

摘要

In this review are classified and analyzed structural parameters of almost 90 monomeric organoplatinum complexes with inner coordination spheres consisting of PtPCOX (X = N, Cl, S), PtPCNX (X = Cl, S, Br, I, As) and PtPCClX (X = S, I, As). These complexes crystallized in three crystal systems: orthorhombic (x 11), triclinic (x 32) and monoclinic (x 45). Distorted square planar arrangements about the Pt(II) atoms are provided by mono-, heterobi- and heterotridentate donor ligands. The chelating ligands create a wide variety of four-, five- and six-membered metallocyclic rings and the effects of both steric and electronic factors influence the L-Pt-L bite angles. There are wide variations in the trans-positions of the donor ligands. Two examples are classified as distortion isomers.
