Abstract

original image

In the μ-carbido complex(4), obtained as shown below, the tin atom is linked to the rhenium atoms via a carbide carbon atom which bonds like a carbyne to the rhenium (TPP stands for tetraphenylporphyrin). An impression of the spatial arrangement of the complexes of type (3), which are formed at only slightly higher temperatures than (4), is provided by the adjacent formula.
