Abstract

The dialumane [Al2][Na(Ph2pz)3]2 (1) has been prepared by the reaction of Na(Ph2pz) with a metastable solution of AlCl. The structure of 1 contains two hydrotris(pyrazolyl)borate-like Na(Ph2pz)32− moieties that are coordinated to each Al atom of the dialumane in a κ2,κ1-N,N,N fashion and several π-stacking interactions are present between the pyrazolate and phenyl rings. In solution the pyrazolate ligands in 1 are in dynamic exchange, even at −80 °C, which shows the lability of these ligands to the low-valent aluminum centers.
