Crystal structure of tetraphenylphosphonium 2-{l_brace}[(Z)-Hydroxy(phenyl)methylene]ammonio{r_brace}nonahydro-closo-Decaborate: The intramolecular O-H...B{sub 3} hydrogen bond in the [B{sub 10}H{sub 9}NHC(OH)Ph]{sup -} anion

The compound (PPh{sub 4})[B{sub 10}H{sub 9}NHC(OH)Ph] is synthesized and its X-ray diffraction study is performed (120 K, R = 0.0875 for 5531 observed reflections). The NHC(OH)Ph substituent occupies the equatorial position in the polyhedral anion. The orientation of the substituent is stabilized by the intramolecular specific interaction of the OH group with the B atoms of the apical B(1)B(2)B(3) face, which can be considered as a multicenter hydrogen bond (the O...B distances are 3.001, 2.877, and 3.251 A; the H...B distances are 2.00, 2.18, and 2.30 A; and the O-H...B angles are 156{sup o}, 121{sup o}, and 148{sup o})
