Structure of the undecahydrodecaborate anion B 10 H 11 − . Crystal structures of [ Ph 3 PCH 2 Naph ]B 10 H 11 and [ Ph 3 P Et ] 2 B 10 H 10

Abstract The crystal structures of [Ph 3PCH2 Naph]B10H11(I) and [Ph 3PEt]2B10H10 (II) are studied (110 K and room temperature, R = 0.0673 and 0.0609 for 4176 and 953 observed reflections in I and II, respectively).

It is unambiguously determined that protonation of the B10H 2−10 anion proceeds at one of the faces of the apical belt and results mainly in a significant lengthening of the edges of the centered face [Be-Be, 1.948(4) Å; Ba-Be, 1.770(5) Å and 1.787(5) Å].
