“…The latter could lead to the stabilization of higher oxidation states of a metal. 16,17 Salts with [B 11 H 14 ] − , a protonated form of [B 11 H 11 ] 4− , have been known since 1962. 18 In the 1970s, a synthesis of the [B 11 H 14 ] − ion was developed using sodium borohydride and boron trifluoride etherate as starting materials, which made this anion accessible.…”

“…After a few days, K Similar high oxidation states of the metals were observed for analogous nickel (+IV), copper (+V) and silver (+V) complexes. 16,17 The reason for this high oxidation state is the electron-rich [B 11 H 11 ] 4− ligand, which also has a large negative charge. Large electron density on the 4s and 4p orbitals of these metals (Co, Ni, Cu) leads to stronger shielding of the electrons on the 3d orbitals.…”

“…Due to the lower electronegativity of the boron atom and the larger negative charge of the anion, nido -[B 11 H 11 ] 4– as a ligand to a metal releases significantly more electron density than C 5 H 5 – . The latter could lead to the stabilization of higher oxidation states of a metal. , …”

The unusually high oxidation state + IV of cobalt is stabilized by ligands based on [B 11 H 11 ] 4− in dark blue colored Cs 4 [Co(B 11 H 10.11 (OH) 0.75 ) 2 ]•4.56H 2 O, K 4 [Co-(B 11 H 9.19 (OH) 1.81 ) 2 ]•2H 2 O, Cs 8 [Co{(B 11 H 6 ) 2 (O)(O 2 BOH) 4 }] 2 •4H 2 O and K 4 [Co-{(B 11 H 6 ) 2 (O 2 BOH) 5 }]•7H 2 O. These compounds were obtained by reacting Co 2+ salts with [B 11 H 14 ] − under alkaline conditions. In the absence of oxygen, Co(+III) compounds such as the light brownish K 4 [Co(B 11 H 11 )(CN) 3 ]•KCl•2.5H 2 O are formed. The title compounds were characterized by X-ray crystallography. Cs 8 [Co{(B 11 H 6 ) 2 (O)(O 2 BOH) 4 }] 2 •4H 2 O and K 4 [Co-(B 11 H 11 )(CN) 3 ]•KCl•2.5H 2 O were also characterized using IR-, UV−vis and cyclovoltammetry. Magnetic measurements of Cs 4 [Co(B 11 H 10.11 (OH) 0.75 ) 2 ]•4.56H 2 O and ESR measurements of Cs 8 [Co{(B 11 H 6 ) 2 (O)(O 2 BOH) 4 }] 2 •4H 2 O show that in these Co(+IV) lowspin d 5 complexes the unpaired electron is on the d x2−y2 , d xy (E 2g ) orbitals.

The structural chemistry of boron goes beyond the sp, sp 2 , and sp 3 hybridization paradigms of carbon chemistry. We relate the apparently unconnected polyhedral boranes and 3D allotropes on the one hand and 2D clusters, borophenes, and multilayer borophenes on the other hand, through an extended Rudolph diagram. Allboron equivalents of cyclopropenium cation viz the flat B 3 H 5 and the nonplanar B 3 H 6 + constitute the missing links. The nonplanar B 3 H 6 + (C 3v ) is the starting point for construction of polyhedral boranes; e.g., fusion of two of them leads to octahedral B 6 H 6 2−. On the other hand, planar B 3 H 6 + and B 3 H 5 relate to borophenes with hexagonal holes. These borophene sheets can be further stacked with diverse interlayer BB bonds, ranging from bilayers to infinite layers. The tendency to achieve electron sufficiency as in the parent C 3 H 3 + dictates the preference for hexagonal holes in the constituent layers and the interlayer bonds between them in multilayer borophenes. The design principles and theoretical validations for the formation of multilayer borophenes are also presented, indicating the variety and complexities involved.
