“…These are in principle close analogues of the present dipalladium species [(PPh 3 ) 2 (µ-PPh 2 )Pd 2 B 9 H 8 (OEt) 2 ] (1), except that each of the reported formulations for compounds 4-7 implies one cluster electron fewer than for compound 1. In the reports of compounds 4 to 7 the location of cluster hydrogen atoms is not addressed, and no cluster 11 B and 1 H NMR data are presented [17][18][19] . The formulations [(PPh 3 ) 2 (µ-PPh 2 )Pt 2 B 9 H 6 (OEt) 3 ], [(PPh 3 ) 2 (µ-PPh 2 )-Pt 2 B 9 H 6 X-(O iso Pr) 2 ] (X = H, Cl) and [(PPh 3 ) 2 (µ-PPh 2 )Pt 2 B 9 H 6 (O iso Pr) 3 ] imply paramagnetic odd-electron species, which in turn may imply intense UV/VIS absorptions, but in the reports on 4, 5, 6 and 7 their colours were not recorded.…”

PdCl 2 (PPh 3 ) 2 ] and the [NHEt 3 ] + salt of [B 10 H 10 ] 2-in refluxing ethanol yield the dipalladaundecaborane cluster compound [7,8-(PPh 3 ) 2 -7,8-(µ-PPh 2 )-9,11-(OC 2 H 5 ) 2 -nido-7,8-Pd 2 B 9 H 8 ](1). An all-atom single-crystal synchrotron X-ray diffraction study shows a significant difference to four structurally characterised platinum congeners reported in the literature for which revised formulation is now necessary. The importance of taking into consideration the electron count in polyhedral boron-containing cluster systems in the course of their characterisation is emphasised.Geometrically closo twelve-vertex bimetallic metallaborane clusters containing two Group-10 transition-metal elements, in which the metal atoms are held in adjacent positions by the borane framework -the 'B-frame' -of the cluster, are of interest as they have been shown to engender an unusual activity across the metal-metal vector 1-3 that resembles the reactivity found in the well-studied field of 'A-frame' compounds 4,5 , and thereby has considerable potential for useful development 3 . Eleven-vertex nido-type metallaundecaborane clusters containing Group-10 transition-element centres are

The review covers the fifty-year period of chemistry of the closo-decaborate anion [B10H10]2– from the first report by Hawthorne and Pitochelli. The main attention is paid to reactions of substitution of various atoms and groups for hydrogen atoms. The general stability of the closo-decaborate cage, including its protonation, cage-opening and cage oxidation reactions, is considered as well. A review with 242 references.
