| Abstract: | The title anion was synthesized by heating dimethylformamide (DMF) solution of the known Ni‐centered and Ni(CO)‐capped tin clusters Ni@Sn9Ni(CO)]3?. The new anion represents the first example of face‐fused nine‐atom molecular clusters. The two clusters are identical elongated tricapped trigonal prisms of nido‐Sn8Ni(CO)]6? with nickel at one of the capping positions. They are fused along a triangular face adjacent to a trigonal prismatic base and made of two Sn and one Ni atoms. The new anion is structurally characterized by single‐crystal X‐ray diffraction in the compound (K222‐crypt])4Sn14Ni(CO)]?DMF. Its presence in solution is corroborated by electrospray mass spectrometry. |
