Abstract
Deboronation of the 11-vertex metallatricarbadecaboranes 1-(η5-C5H5)-2-Ph-closo-1,2,3,4-M-C3B7H9 [M = Ru, Fe] and 1,1,1-(CO)3-2-Ph-closo-1,2,3,4-M-C3B7H9 [M = Re] with tetrabutylammonium fluoride (TBAF) produced the first examples of the 10-vertex families of closo and nido metallatricarbanonaborane complexes, 2-(η5-C5H5)-10-Ph-closo-2,1,6,10-M-C3B6H8 [M = Ru (1), Fe (2)] and 5,5,5-(CO)3-10-Ph-nido-5,6,9,10-Re-C3B6H9– (3). Crystallographic characterizations of 1 and 3 confirmed geometries, based on a bicapped square antiprism for 1 and a bicapped square antiprism with one missing vertex for 3, that are consistent with their respective 22 (closo) and 24 (nido) skeletal-electron counts.Keywords
