The structural chemistry of boron goes beyond the sp, sp2, and sp3 hybridization paradigms carbon chemistry. We relate apparently unconnected polyhedral boranes 3D allotropes on one hand 2D clusters, borophenes, multilayer borophenes other hand, through an extended Rudolph diagram. All-boron equivalents cyclopropenium cation viz flat B3H5 nonplanar B3H6+ constitute missing links. (C3v) is starting point for construction boranes; e.g., fusion two them leads to octahedral B6H62–. On planar with hexagonal holes. These borophene sheets can be further stacked diverse interlayer BB bonds, ranging from bilayers infinite layers. tendency achieve electron sufficiency as in parent C3H3+ dictates preference holes constituent layers bonds between borophenes. design principles theoretical validations formation are also presented, indicating variety complexities involved.

The unusually high oxidation state + IV of cobalt is stabilized by ligands based on [B11H11]4– in dark blue colored Cs4[Co(B11H10.11(OH)0.75)2]·4.56H2O, K4[Co(B11H9.19(OH)1.81)2]·2H2O, Cs8[Co{(B11H6)2(O)(O2BOH)4}]2·4H2O and K4[Co{(B11H6)2(O2BOH)5}]·7H2O. These compounds were obtained reacting Co2+ salts with [B11H14]− under alkaline conditions. In the absence oxygen, Co(+III) such as light brownish K4[Co(B11H11)(CN)3]·KCl·2.5H2O are formed. title characterized X-ray crystallography. also using IR-, UV–vis cyclovoltammetry. Magnetic measurements Cs4[Co(B11H10.11(OH)0.75)2]·4.56H2O ESR show that these Co(+IV) low-spin d5 complexes unpaired electron dx2–y2, dxy (E2g) orbitals.
