Heterocomplex-based graphite lamellar compounds: C22CuAl2Cl8.5 and C10Cd0.2AlCl3.7: Intercalation pathway, structure and transport Original Research Article

Attempts to intercalate the chloroaluminate complexes CuAl2Cl8 and CdAl2Cl6 into graphite have resulted in the synthesis of two new first stage compounds, C22CuAl2Cl8.5 and C10Cd0.2AlCl3.7. The former possesses an oblique inplane unit cell, the latter a rectangular cell, commensurate with that of the host lattice. The electrical resistivity has been studied within (ϱa) and perpendicular (ϱc) to the basal planes from 295 to 4.2 K. Both dϱadT and dϱcdT are positive (metallic) and the anisotropy ϱcϱa lies between 105 and 106 over the full temperature range. The data are analyzed and discussed in terms of the structure and current transport theories.
