Abstract
Reaction of the nido ten-vertex iridaborane [ sym-6,6,6-H(PPh 3)(PPh 2- ortho- C 6H 4)-nido-6-IrB 9H 12-5 ] ( 1) or its uncyclized analogue 2 with KH followed by cis-[PtCl 2(PMe 3) 2] yields the orange-red air-stable complex [7,7- (PMe 3) 2-9,9,9-H(PPh 3)(Ph 2P- ortho- C 6H 4)-nido-7,9-PtIrB 9H 10-4 ] ( 3) or the corresponding acyclic analogue ( 4). Compound 3 has been characterized by multi-element NMR spectroscopy and by X-ray crystallography. It crystallizes in the monoclinic space group C2/c with a = 4072.1(8), b = 1509.2(4), c = 1912.9(4) pm, β = 110.63(2)°, Z = 8, and the structure ( R = 0.047 from 5641 reflections) is that of an eleven-vertex nido-dimetallaundecaborane with non-adjacent metal atoms in its open face, and has similarities to the structures of related nido-mono- metallaundecaboranes. During the course of the reaction the starting compounds 1 and 2 are shown to undergo a cluster rearrangement that may also play a role in many hitherto ostensibly disparate ten-vertex cluster reactions.
