Stable Free Dianionic Silico[BOND]Carbon Clusters

Abstract

original image

Structural characteristics significantly different to those of neutral Si[BOND]C clusters are exhibited by isolated dianionic Si[BOND]C clusters. The theoretical investigation of small, stable dianionic Si[BOND]C clusters indicates that the free dianions SiCmath image (1) and Simath image (2) are capable of existence. These molecules are predicted to be sufficiently long-lived that they should be observable in a mass spectrometer.
