Organophosphines in organoplatinum complexes: Structural aspects of PtP2CX (X = NL or BL)derivatives

• Structure of PtP2CX (X = N,B).
• Review of 60 complexes.
• Attention to any trans-influence.
• Isomers.

In this review are summarized and analyzed structural parameters of over sixty monomeric complexes with PtP2CX (X = NL or BL) chromophore. These complexes crystallized in five crystal systems: trigonal (x2), tetragonal (x2), triclinic (x15), orthorhombic (x17) and monoclinic (x29). The inner coordination spheres are build up by monodentate: (NL, CL, BL, PL), homobidentate (P,P′), heterobidentate (C/N; C/P, N/P) and heterotridentate (P/C/P; P/N/P, P/N/C) donor ligands. The chelating ligands form wide variety of metalocyclic rings: three-, four-, five-, six-, and even seven-membered and the effect of both electronic and steric factors influence on the L-Pt-L bite angles. In generally, an inner coordination sphere in the complexes with cis-configuration is somewhat more crowded than those with trans-configuration.
