The THF content of these compounds is rather low and an increasing aggregation is observed with the size of the metal atom. Thus, tetrameric [(THF)<sub>2</sub>Ca{μ-N(H)Ph}<sub>2</sub>]<sub>4</sub> (<b>2</b>) and polymeric [(THF)<sub>2</sub>Sr{μ-N(H)Ph}<sub>2</sub>]<sub>∞</sub> and {[(THF)<sub>2</sub>Ba{μ-N(H)Ph}<sub>2</sub>]<sub>2</sub>[(THF)Ba{μ-N(H)Ph}<sub>2</sub>]<sub>2</sub>}<sub>∞</sub> show six-coordinate metal atoms with increasing interactions to the π systems of the phenyl groups with increasing the radius of the alkaline earth metal atom.
