A multinational research team has created a drum-shaped cobalt-boron species in the gas phase, CoB16, which sets a record for highest coordination number in a molecule. The sandwich complex created by Alexander I. Boldyrev of Utah State University, Lai-Sheng Wang of Brown University, and their colleagues consists of two B8 rings connected to the central cobalt atom via 16 bonds, the theoretical maximum based on the number of . . .
