Abstract

•Structural aspect of organophosphines in organoplatinum complexes.•Monomeric complexes with PtPC3 and PtP2CX chromophores.•Cis-trans-, and distortion isomers.•Attention to any trans-influence.

In this review are summarized and analyzed structural parameters of over one hundred monomeric complexes with PtPC3 and PtP2CX (X = H, F or OL) chromophores. These complexes crystallized in four crystal systems: trigonal (×1), orthorhombic (×14) triclinic (×22) and monoclinic (×70). The inner coordination sphere (PtPC3) is build up by monodentate (PL,CL), homobidentate- (C,C), heterobidentate- (C,P) and even homotridentate- (C,C,C) donor sites ligands. The PtP2CH is build up by monodentate (PL, CL and H atom), homobidentate- (P,P), heterobidentate- (C,P) and even (H,P) donor sites ligands. The PtP2CF by monodentate (PL, CL and F atom) and homobidentate- (P,P) donor sites ligands. The PtP2CO, by monodentate (PL, CL and OL), homobidentate- (P,P), heterobidentate- (P,C; P,O; and O,C) and heterotridentate- (P,C,P) donor sites ligands. The chelating ligands form wide variety of metallocycles with three-, four-, five-, six- and even seven-membered rings. There are two types of isomers cis-, trans- and distortion, the latter prevails. Several relationships were found and discussed. Noticeable, while PtP2CH complexes with cis-configuration are somewhat less crowded but higher distorted than those with trans-configuration, in the complexes with PtP2CX (X = F or O) inner coordination spheres opposite is true.
