A new Al-Cr phase structurally similar to triclinic Al 11 Mn 4 was revealed at about Al 3 Cr composition. It is formed between 700 and 800 °C by a peritectoid reaction from Al 4 Cr and the low-temperature γ-phase. The Al 4 Cr-phase was confirmed to

The C 60 ONCFn cycloadduct (Fn=ferrocene) was prepared in the reaction between C 60 and ferrocene oxime, the ferrocene derivative was bound to C 60 at the 6–6 bond by a heterocyclic oxygen–nitrogen–carbon ring; the compound was stable in air. T

Molecules that may adopt various stable conformations might be applied to store information. The conformational changes could be induced by suitable polarized tip of STM. For the STM experiments two types of fullerene:ferrocene cycloadducts (C60:Fn)

Methylnaphthalenes form mixed crystals with C 60 . The molecules in these crystals are so densely packed, that the flat methylnaphthalene molecules undergo a deformation. The deformation is observed by the shift of the characteristic infrared and Ram

Iron in the fullerite lattice binds fullerences in a sandwich type C60FeC60 complexes. At the concentration C60Fe2 it crystallizes in the monoclinic lattice. The structure is thermally unstable, with the energy release of 606 kJ·mol−1 it returns t

Fullerences C60 with adamantane (C10H16), hexamethylotetramine (HMT, C6H12N4) or 1,4-diazabicyclooctane (DABCO, C6H12N2) crystallize, at the relative concentration C60/guest=2/1, in the pseudotetragonal lattice in which C60 retains almost the same po

C 60 forms solvates with dimethylnaphthalenes (DMNAP) of either 1:1 or 1:2 molar ratio. All these solvates crystallize in the triclinic lattice with different lattice parameters. The C 60 (DMNAP) 2 solvates decompose at approximately 80–120°C to t
