摘要：

The reaction of the arachno-6-(CH3C(O)CH2)5,6,7-C3B7H11- tricarbaborane monoanion with CpFe(CO)(2)I yields the first example of a metallacarborane complex containing five cage carbon atoms: nido-2-(eta(5)C(5)H(5))Fe-7-CH3-7,8,9, 10, 12-C5B6H10(1). A single-crystal X-ray study established that, in agreement with its 28-skeletal-electron count, the cage adopts a nido-type structure based on, a 13-vertex docosahedron missing one six-coordinate vertex. All five carbons are situated on the open six-membered face and exhibit carbon-carbon and boron-carbon distances in the normal ranges found in metallacarboranes.
