Stereochemistry of complex inorganic compounds. XXXV. Complex containing a ligand that spans trans positions

Quantitative measurement of the reduction of platinum(iv) complexes using X-ray absorption near-edge spectroscopy (XANES)

“…Hydrogen peroxide was sourced from Ajax Chemicals, and stored at 5 1C in the dark. cis-[PtCl 2 (NH 3 ) 2 ] (cisplatin) was prepared using the methods reported by Boreham et al, Dhara, and Hoeschele et al [16][17][18] cis-[PtCl 4 (NH 3 ) 2 ], cis,trans,cis-[PtCl 2 (OAc) 2 (NH 3 ) 2 ], and cis,trans,cis-[PtCl 2 (OH) 2 (NH 3 ) 2 ] were prepared as described in Hall et al 19 trans-[PtCl 2 (NH 3 ) 2 ] (transplatin) was prepared using the method reported by Kauffman et al 20 trans-[PtCl 4 (NH 3 ) 2 ] was prepared using methods by van der Veer et al and Mochida et al 21,22 cis-[Pt(NH 3 ) 2 (OH) 4 ] was prepared as described by Brandon et al 23 [PtCl 2 (en)] (en = ethane-1,2-diamine), [PtCl 4 (en)], cis,trans-[PtCl 2 (OH) 2 (en)], and [PtCl 2 (OAc) 2 (en)] were prepared as described by Ellis et al 24 cis-[PtCl 2 (py) 2 ] (py = pyridine) was prepared as previously described by Kauffman. 25 The geometry of cisplatin and transplatin was confirmed using the Kurnakov test.…”

Exposed Equatorial Positions of Metal Centers via Sequential Ligand Elimination and Installation in MOFs

“…Trans -chelating or trans -spanning ligands are bidentate ligands that bind the opposite sites of a complex with square-planar geometry at or near a 180° angle . Although a far larger number and variety of cis -chelating ligands than trans -chelating ones have been developed for catalysis and their chemistry is more thoroughly explored, catalysts containing trans -chelating ligands may display alternative chemistry, activity, and selectivity in various catalytic processes.…”

Synthesis and Properties of TRANSDIP, a Rigid Chelator Built upon a Cyclodextrin Cavity: Is TRANSDIP an Authentic trans‐Spanning Ligand?

“…It is noteworthy that the first trans ‐spanned diamine complex was fully characterised in 1975,12 although its synthesis was already reported in a Thesis published in 1946 13…”
