X-Ray crystal and molecular structure of [Et2NCFe(CO)3]2: an example of the division of an alkyne into two separate units by rupture of the C
C bond
Abstract
X-Ray crystallography of the complex [Et2NCFe(CO)3]2 obtained from Fe(CO)5 and Et2NCCNEt2 indicates rupture of the carbon–carbon triple bond during the formation of this iron complex to give two separate bridging Et2NC (diethylimmoniocarbene) units.
