The presence of cobaltdibismuth triangular faces in the lowest energy deltahedral cobaltadibismaborane polyhedra: Major differences from their cobaltadiphosphaborane analogues

Density functional theory studies on CpCoBi2BnHn (n = 7, 8, 9) indicate an energetic preference for structures with Bi2Co faces and Bi-Bi edges in contrast to the analogous CpCoP2BnHn and CpCoC2BnHn+2 derivatives.250
