Formation, properties, and thermal decomposition of bisarene chromium(i) and molybdenum(i) fullerides

Fullerene complexes with bis(η6-hexamethylbenzene)chromium, hexamethylbenzene, and hexaethylbenzene

“…A saturated solution of hexa methylbenzene in о Cl 2 C 6 H 4 was added to a saturated solution of fullerene (0.06 g) in о Cl 2 C 6 H 4 , and the mixture was stirred for 30 min. The solvent was decanted and the black crystalline precipitate of compound 2 was washed with hexane and dried in vacuo (7), 2.1309 (10), 2.0867 (6), 2.0608 (6), 2.0304 (7), 1.9741 (7), 1.8976 (6), 1.8737 (7), 1.8571 (6). IR (mineral oil), ν/cm -1 : 1428, 1182, 577, 526 (C 60 ); 1080 br, 796 (C 6 Ме 6 ).…”

Thermodynamics of bis-(η6-diphenyl)chromium (I) fulleride [(η6-Ph2)2Cr]+[C60]− in the range from T→(0 to 360)K

“…The sample of bis-(g 6 -diphenyl)chromium (I) fulleride was synthesized by the method described earlier [5,12]. The solution of [(g 6 -Ph 2 ) 2 Cr] 0 in toluene was added to a saturated solution of C 60 in toluene at room temperature.…”

“…The X-ray diffraction study [7,12] showed that the complex is a centro-symmetrical dimer at T = 100 K (figure 1) and monomer at room temperature. The ion structure of the fulleride complex was confirmed by ESR spectra [12] that were recorded on a ''Bruker ER 200D-SRC'' spectrometer equipped with an ER 4111 VT temperature-controlled unit [12]. Since the studied sample was not stable the all manipulations were performed in a glove box in a flow of high-purity dry argon.…”

Harnessing the Synergistic and Complementary Properties of Fullerene and Transition-Metal Compounds for Nanomaterial Applications

“…[282] Examples of transition metal doped fullerides are less abundant, and are summarised in Table 7. Among the transition metals fulleride compounds most common are smaller first row transition metals derivatives, with various examples of Cr compounds [285][286][287][288][289][290][291][292][293][294][295] as well as Ti, [283] V, [284] Mn, [296] Ni, [296,297] Fe [296,297] and Cu. [297] A few examples of larger second row transition metals such as Mo, [295,298] Pd, [299] Ag [297] and Cd [296], Pt [299][300][301] and Au [302] of the third row have also been reported.…”
