Volatile Methylplatinum Complexes – Formation and Reactions in Anhydrous HF

Abstract

are obtained by ligand exchange reactions. The thermal stability of the complexes increases in the given sequence, whereas their volatility decreases. Demethylation reactions with anhydrous HF [a] 1197 cleave one methyl group. The addition of AsF 5 and SbF 5 often cleaves both methyl groups. The resulting L 2 Pt 2+ compounds are obtained in crystalline form with the corresponding [AsF 6 ] -, [SbF 6 ] -, [Sb 2 F 11 ] -, and [B 12 F 12 ] 2anions. Bridged dimeric or trimeric platinum complexes are also formed.

Understanding the electron-stimulated surface reactions of organometallic complexes to enable design of precursors for electron beam-induced deposition

“…The ligand variation scheme (Fig. 17) is analogous to the one for Au(I) complexes incorporating several known compound types, such as PtX 2 (CO) 2 [73], PtR 2 (CO) 2 [74], PtR 2 (PF 3 ) 2 [74], and X 2 Pt(CNR 0 ) 2 [75]. Such studies would be an important step toward developing a set of coherent design rules for EBID precursors.…”

Inner-Sphere versus Outer-Sphere Coordination of BF4– in a NHC-Gold(I) Complex

“…17 For these putative species, the second coordination site on the gold (I) center 33 nickel, 34 copper, 35 zinc, 36 rhodium, 37 silver, 38 and platinum. 39 The few reported complexes [M(L) n (X) n ] that bear at least one NHC ligand are non-coinage metal ones, with palladium (n = 1, X = FBF 3 ), 40 ruthenium (n = 2, X = FBF 3 ) 41 and indium (n = 1, X = FSbF 5 ) 42 Figure 1a). 19 This remarkable complex contains both innerand outer-sphere PF 4 -fragments.…”

Synthesis and Structural Characterization of an Unusual Platinum π-Arene Complex: (η6-C6H3Me3)Pt[(C2F5)2PMe]Me+

“…9,24 The short Pt−P bond distance of 2.1620(7) Å is in keeping with the generally observed trend for PFAP complexes. 25 Relative to other structurally characterized Pt(II)−PFAP systems, this bond distance falls within the range 2.135−2.186 Å found for Pt(II)−PFAP with weak trans influence groups such as trifluoroacetate, 13,19 triflate, 26 pentafluoropyridine, 13 and fluoroarsenate as well as antimonate anions, 27 suggesting that the effective trans influence of the π-arene ligand in complex 1 is low.…”
