Abstract
Abstract This review covers over fifty Pt (II) complexes of the compositions PtP3X (X = H, OL, NL, BL, Cl, SL, Br, or I). These complexes crystallized in three crystal classes: monoclinic (23 examples) triclinic (17 examples) and orthorhombic (11 examples). The PtP3Cl is most common with 23 examples. There are variable combinations of organophosphines monodentate – P; bidentate- P,P; P,N; P,B; and tridentate – P,P,P; P,O,P; P,N,P; and P,S,P. The structural parameters (Pt–L, L–Pt–L) are analyzed and discussed with an attention to the distortion of a square-planar geometry about the Pt (II) atoms as well as of trans-influence. The sums of Pt–L (x4) bond distances growing with covalent radius of the X-atoms.
Highlights
The high affinity of the platinum(II) ion for phosphorous enables it to bind effectivity to organophosphines
Another review covers structural data of monomeric platinum(II) coordination complexes with an inner coordination spheres
This review includes over fifty monomeric Pt(II) coordination complexes with composition of PtP3X (X = H, OL, NL, BL, Cl, SL, Br, or I)
Summary
The high affinity of the platinum(II) ion for phosphorous enables it to bind effectivity to organophosphines. There are numerous published structural studies on platinum complexes which were classified and analyzed (Holloway and Melník, 2002, 2003, 2004). Research activity on this field is always very active. We classified and analyzed structural data of monomeric organoplatinum complexes with PtP3C inner coordination sphere (Melník and Mikuš, 2017). PtP4, PtP3X (X = H, F, O, N, Cl, S, Br, or I) and PtP2X2 (X = H, F, O, N, CN, or B) in which P-donor ligands are monodentate organomonophosphines (Melník and Mikuš, 2015) The aim of this survey is to correlate the structural parameters available, for PtP3X (X = H, OL, NL, BL, Cl, SL, Br, or I) derivatives with variable combinations of organophosphines. The data are comparing and discuss with PtP3X in which P-donor ligands are only monodentate organomonophosphines
