Ch. Hu et al., ORTHO-CYCLOBORONATION OF A THIOBENZOATE CLUSTER - [(PPH3)(PHCOS)(2)NIB10H10].0.5C(6)H(14), Acta crystallographica. Section C, Crystal structure communications, 53, 1997, pp. 695-697
The title compound, 2,7:3,7-di(mu-thiobenzoato-S:O)-7- (triphenylphosp
hine-P)-8,9:10, 11-di-mu H-7-nickela-nido-undecaborane-hexane (1/0.5),
C32H35B10NiO2PS2 . 0.5C(6)H(14), has been synthesized and characteriz
ed by X-ray diffraction analysis. The Ni atom is bound to one PPh3 lig
and, two S atoms and four B atoms of the {NiB10} cage. The ortho-cyclo
boronation of thiobenzoates produces two five-membered Ni-S-C-O-B ring
s.
