Abstract
Abstract Structural data of cis-Pt(η2-P2L)(XL)2 (X = Ge or Te), cis-Pt(η2-P2L)(η2-X2L) (X = As, Ge or Te) and trans-Pt(η2-P,TeL)2 were classified and analyzed. The chelating ligands create varieties of metallocyclic rings, which open in the sequence: 83.1° (GeGeGe) < 83.8° (AsC2As) < 86.2° (PC2P) < 88.5° (PC2Te) < 89.7° (PC3P) ~ 89.7° (GeGe2Ge). The structural data are compared and discussed with the complexes of an inner coordination spheres Pt(η2-P2L)(XL)2 (X = O, N, CN, B, Cl, S, Se, Si, Br or I), Pt(η2-P2L)(η2- X2L) (X = O, N, S, Se or Si), and Pt(η2-P,SiL)2.
Highlights
Comprehensive view on structural parameters of almost monomeric platinum complexes shows, that the square-planar Pt(II) complexes, by far prevail (Holloway and Melnik, 2002, 2003, 2004)
The chelating donor ligands create varieties of metallocyclic rings which open in the sequence: 83.1° (GeGeGe) < 83.8° (AsC As) < 86.2° (PC P)
Summary
Comprehensive view on structural parameters of almost monomeric platinum complexes shows, that the square-planar Pt(II) complexes, by far prevail (Holloway and Melnik, 2002, 2003, 2004). One of such interest of a square-planar Pt(II) complexes is anti-tumor activity of Pt(NH ) Cl , known as “cisplatin” There are numerous published structural studies of organomonophosphines platinum complexes, which were classified and analyzed (Melník and Mikuš, 2015). There are numerous structures of Pt(II) complexes with organomonophosphines (Holloway and Melnik, 2002, 2003, 2004; Melník and Mikuš 2019a, 2019b, 2020; Melník et al, 2019). The aim of this review is to classified and analyzed structural parameters of cis-Pt(η2-P L)(XL)
