“…Compound 1 is the first platinum–chrysene compound whose structure has been confirmed by X‐ray diffraction 3. It should be noted that among platinum‐group metals only ruthenium–chrysene compounds have been described previously 11–13. In contrast to these compounds, which have an η 6 ‐type coordination, the chrysene in 1 is coordinated in an η 2 ‐mode.…”

One‐Step Synthesis of a Platinum(0)–Gallium(III) Chrysene Complex

Recent investigations of gallium(iii) halide-aromatic solvent systems with respect to platinum-group metal halides have shown them to be very efficient reducing media. [1, 2] Another attractive feature of gallium(iii) halides is their aptitude to abstract halide ions from other metal halides, which facilitates metal-metal bond formation. Taking advantage of these properties, we have prepared and crystallographically characterized a series of dipalladium(i) and diplatinum(i) complexes [M 2 (h 6 -arene) 2 (GaX 4 ) 2 ] (arene = benzene, its alkylated derivatives, or naphthalene; X = Cl À or Br À ).

“…These separations are in agreement with the analogous distances in 7 , but in contrast to the ca. 2.18−2.24 Å range of Ru−C(cymene) values found in complexes of pyrazolylmethane and pyrazolyl borate, among others. − Close inspection of the Ru−C(cymene) bond lengths in 6 reveals that the distances Ru−C12 and Ru−C13 are shorter than Ru−C9 and Ru−C10, suggesting a “tilted” mode of coordination. The aromatic C−C bond lengths within the arene, ca.…”

“…1.39-1.44 Å are as expected. [19][20][21][22][23][24][25][26][27][28] One of the most interesting features of the structure concerns the ca. 45°twist made by the arene C11-C17 vector, relative to a symmetric position defined by the metal and the two P atoms.…”

Enantioselective Homogeneous Catalysis and the “3,5-Dialkyl Meta-Effect”. MeO−BIPHEP Complexes Related to Heck, Allylic Alkylation, and Hydrogenation Chemistry

et al. 1997

The enantioselectivities arising from a Pd-catalyzed Heck reaction (>98% ee) and an allylic alkylation (>90% ee) using a 3,5-di-tert-butyl-MeO−BIPHEP chiral auxiliary (1) are reported. Higher ee's are observed with the 3,5-dialkyl substituents than with the unsubstituted parent MeO−BIPHEP. It is proposed that the observed dialkyl “meta-effect”, on enantioselectivity, is the combined result of a more rigid and slightly larger chiral pocket and that this effect will have some generality in homogeneous catalysis. Detailed NMR studies on the allyl complex [Pd(PhCHCHCHPh)(1)]PF6 (5), and the model hydrogenation catalyst [RuH(cymene)(1)]BF4 (6), reveal restricted rotation about several of the P−C(ipso) bonds of the phosphorus substituents containing the 3,5-di-tert-butyl groups. The X-ray structure of 6 reveals that the cymene ligand is not symmetrically bound to the Ru atom. This observation is interpreted as an expression of the chiral pocket of 1. MM3* calculations on 6 support the NMR findings and reproduce the X-ray results.

“…While Perylene has been utilized in the synthesis of multiple charge transfer salts, it has also been integrated into organometallic complexes having ruthenium, palladium and silver metal centers and as essential components within Perylene 3,4:9,10-tetracarboxylic acid bisimides (PBIs), the latter being building blocks having applications as pigments, protein tags, and within organic field effect transistors (OFETs) and organic solar cells due to their robust photochemical, thermal stability and high fluorescence quantum yields [13][14][15][16][17][18][19][20][21][22]. In addition to these, Perylene has also been co-crystallized with various organic acceptors, among them TCNQ (TCNQ = 7,7,8,8-tetracyanoquinodimethane) with which it forms both 1:1 and 3:1 phases and fluoranil (fluoranil = 2,3,5,6-tetrafluoro-1,4-benzoquinone), complexes known to be photoconductors [23][24][25][26][27].…”

Utilizing Perylene in New Organic Donor–Acceptor Materials: Highlighting the Synthesis, Structure and Physical Properties of Perylene-pDNB and Perylene-TCNP

In this communication, we present the syntheses, structure, infrared (IR) spectroscopic, and electronic transport properties for two new Perylene-containing donor-acceptor complexes, Perylene-pDNB (1) and Perylene-TCNP (2). The 2:1 complex with pDNB, complex 1, crystallizes in the triclinic space group P " 1 with cell dimensions a = 7.7488(12) Å , b = 9.7125(15) Å , c = 10.6864(17) Å , a = 80.829(7)°, b = 84.893 (7)°and c = 89.495(6)°, while complex 2, the 1:1 complex with TCNP, crystallizes in the orthorhombic space group Cmca with a = 18.264(4) Å , b = 7.405(2) Å and c = 14.674(3) Å . Structural features of the constituent donor and acceptor molecules were compared to those for the free components and, when coupled with IR spectroscopic measurements, suggested that both complexes contained neutral components. This conclusion was further supported by electronic transport measurements that revealed both complexes to be insulators. Graphical Abstract Herein we present the structure and both the IR spectroscopic and transport properties for new
