Iron carbonyl C화학적 특성, 용도, 생산

화학적 성질

Mobile, yellow liquid.Evolves carbon monoxide on exposure to air or light. Soluble in nickel tetracarbonyl and most organic solvents; soluble with decomposition in acids and alkalies; insoluble in water.

화학적 성질

Iron pentacarbonyl reacts with cyclopentadiene at 135° in an autoclave to give the binuclear complex [(π-C5H5)Fe(CO)2]2 as deep reddish-purple crystals which are stable to air and water. The crystal structure determination shows this molecule to be centrosymmetric with two bridging carbonyls forming a plane with the two iron atoms [Fig. 19(a)]. The rather short Fe-Fe distance of 2-49 ? and the diamagnetism of the compound indicate the presence of the Fe-Fe bond. In solution, however, it tautomerizes to the structure believed to be that shown in Fig.19(b),in which the two rings lie on one side of the mean plane formed by the bridging carbonyl groups and the iron atoms and the two terminal CO groups lie on the other side.

용도

Iron pentacarbonyl is a useful dehalogenating and carbonylating agent.

용도

Catalyst in organic reactions, carbonyl iron for high-frequency coils.

위험도

Flammable, dangerous fire risk. Toxic by ingestion, inhalation, and skin absorption.

Structure and conformation

The trigonal bipyramidal structure has been preferred to the square pyramidal one in the interpretation of electron diffraction, Raman and infrared and thermodynamic data; the apparently contradictory dipole moment of 0-8 D being attributed to atom polarization. A single crystal X-ray structure determination at - 80°C has confirmed the trigonal bipyramidalstructure.
