B. Stibr et al., THE FIRST EXAMPLES OF METALLATRICARBOLLIDES - ISOMERIC 12-VERTEX CYCLOPENTADIENYL FERRATRICARBADODECABORANES [(ETA(5)-C5H5)-CLOSO-FEC3B8H11], Collection of Czechoslovak Chemical Communications, 60(12), 1995, pp. 2023-2027
The first metallatricarbollides, six isomeric twelve-vertex metallatri
carbaboranes of general structure [(eta(5)-C5H5)-closo-FeC3B8H11], are
formed in the reaction between TI[nido-7,8,9-C3B8H11] and [(eta(5)-C5
H5)-Fe(CO)(2)I] in toluene at reflux. Two of them have so far been sat
isfactorily identified as [3-(eta(5)-C5H5)closo-3,1,2,4-FeC3B8H11] and
[2-(eta(5)-C5H5)-Closo-2,1,8,11-FeC3B8H11] by NMR spectroscopy.
