摘要：

We report the first study of metallocenes, M(eta(5)-C5H5)(2) (M=Co, Fe) in a high-pressure range of P similar to 0-22 GPa at room temperature. The dependencies of the electrical resistance R on P for ferrocene (bis(eta-5-cyclopentadienyl)iron) and cobaltocene evidenced conservation the initial insulating properties but behaved in a different manner. Above P similar to 13-18 GPa both the crystals exhibited a growth of R with P and with time pointing out a possible amorphization. Only R(P) curves for Co(eta(5)-C5H5)(2) exhibited the features which could point to structural transformations.
