Abstract: | The reaction of Ni(C5H5)2 and Ni(C5H4COOCH3)2 with the acetylene (?)-(R)-C6H5CCCONHCH(CH3)(C6H5)(C6H5), “CC′”, yields tetrahedral Ni2C2 clusters. Besides the compounds with two identical Ni corners (Ni2CC′ types) also compounds with two different Ni corners (NiNi′CC′ types) are formed. These consist of two diastereomers which, for a given (R)-configuration in the acid amide substituent, differ only in the cluster chirality. They are separated chromatographically and turn out to be configurationally stable with respect to a change of the cluster chirality. |
