Preparation and Spectroscopic Investigations of Mixed Octahedral Complexes and Clusters

“…A more common type of oxidative ligand exchange is the preparation of fluoro-mixed complexes utilizing BrF 3 . The postulated stereospecific formation of fac -K 2 [PtF 3 Cl 3 ] as the sole oxidation product of K 2 [PtCl 6 ] with BrF 3 has never been verified. , Depending on the reaction conditions, other mixed species [PtF n Cl 6 - n ] 2- have been detected; however, for n = 2, 3, 4, only the cis/fac isomers have been present . Corresponding fluorochloro complexes are known for Re(IV,V), Os(IV,V), and Ir(IV,V). − Octahedral complexes containing the heavier halides, Br or I, together with F are rare, but are known for Pt(IV) and Os(IV), ,, and most notably Re(IV), for which there are many examples of 3-fold mixed species …”

Synthesis, characterization and X-ray crystal structures of polyether and ethylene bridged bis(azolyl) platinum(II) complexes

“…The method used: injector port, 250°C; helium flow rate, 1.10 mL/min; oven temperature, 70°C for 1 min and ramped to 250°C over 10 min. K 2 [PtI 6 ] was obtained as previously described [9]. Numbering of the aromatic rings for NMR assignment is given in Scheme 1.…”

Doubling the Stakes: The Promise of Halide Double Perovskites

“…[52] Since then, many new elpasolites have been synthesized, including Cs 2 AgInCl 6 , [53] Cs 2 AgTlX 6 (X = Cl À , Br À ), [54] Cs 2 AgSbCl 6 , [55] (MA) 2 TlBiBr 6 , [56] and various alloys. [55,57] This recent growth of novel elpasolite compositions has sparked an interest in many K 2 PtCl 6 -type perovskites well-known in the early literature,s uch as Cs 2 Te I 6 , [15] Cs 2 PdBr 6 , [37c] Cs 2 SnI 6 , [58] Cs 2 PtI 6 , [59] and Cs 2 TiI 6 , [60] as researchers reinvestigate these materials in the context of photovoltaics. [18,61] Therecent interest in halide double perovskites as photovoltaic absorbers has led to new applications for these materials [7] while also serving as ap latform for more fundamental studies,s uch as investigations into the consequences of dimensional reduction.…”
