Efficient preparation of a linear, symmetrical, metal–metal
bonded tricobalt compound; should we believe there is a bond stretch
isomer?
The synthesis in 42% yield of a linear, symmetrical, fully Co–Co bonded [2.3178(9) Å] trinuclear complex [Co 3 (dpa) 4 Cl 2 ] [Hdpa = bis(2-pyridyl)amine] is reported, and its crystal structure presented.
