A phosphindolyllithium complex or a lithium salt with a phosphindolyl anion? Both the ease of the synthesis and the structure of compounds 1 are surprising: the unit cell of crystalline 1 b contains two independent molecules in which lithium is coordinated in an η 5 fashion in one and an η 3 fashion in the other—this indicates the transition from the complex to the anion.
