title: Synthesis, structure, and properties of a dialumane supported by pyrazolate ligands.
abstract: The dialumane [Al2][Na(Ph2pz)3]2 () has been prepared by the reaction of Na(Ph2pz) with a metastable solution of AlCl. The structure of contains two hydrotris(pyrazolyl)borate-like Na(Ph2pz)3(2-) moieties that are coordinated to each Al atom of the dialumane in a κ(2),κ(1)-N,N,N fashion and several π-stacking interactions are present between the pyrazolate and phenyl rings. In solution the pyrazolate ligands in are in dynamic exchange, even at -80 °C, which shows the lability of these ligands to the low-valent aluminum centers.
