Abstract
An unusual structural growth pattern has been found in the system of ZrmCn, in which multicage structures are formed. The experimental evidence shows that the first cage closes at Zr8C12. Surprisingly, subsequent cluster growth does not lead to the enlargement of the cage size as it usually does in the case of pure carbon clusters and water clusters, for example. Rather, multicage structures are developed, that is, a double cage at Zr13C22 and Zr14C21/23, a triple cage at Zr18C29, and a quadruple cage at Zr22C35. This feature distinguishes the class of metallo-carbohedrenes from the regular doped fullerenes.Keywords
