Abstract

Allene homologous cumulenes are not always linear! The title compound, which has now been synthesized and structurally characterized, contains a BC₂ unit that is isoelectronic with CO₂ and that deviates by 16° from linearity without losing the double-bond character of the B-C bonds. The BC₂ unit is located in the center of a bicapped trigonal prism of calcium ions (see picture).
