Organophosphines in organoplatinum complexes: Structural aspects of PtPC2X (X = H, O, N, B, Cl, S or I) derivatives

In this review are summarized and analyzed structural parameters of over seventy monomeric organoplatinum complexes with PtPC2X (X = H, O, N, B, CI, S or I) inner coordination sphere. These complexes crystallized in four crystal systems: tetragonal (x2), orthorhombic (x3), triclinic (x 27) and monoclinic (x41). The inner coordination spheres about platinum atoms are built by mono- P, C, H, 0, N, Cl, S, I, bi- C/ C, C/O, C/N, P/N, P/C, P/S, and tri- C/C/B, P/C/C, C/N/C and P/C/N- dentate ligands. There are complexes with cis- and trans-configurations from which the former by far prevails (56 examples) against (8 examples) with trans-configuration. The chelating ligands created wide variety of metallocycles with three, four-, five-, and six-membered metallocyclic rings. There are examples which exist in isomeric forms distortion and ligand isomerism. Several relationships were found and discussed. (C) 2016 Elsevier B.V. All rights reserved.
