Abstract

The 2:3 and 1:2 stoichiometric reactions of N-ethyl morpholine with the Et2O adduct of AlH3, prepared from LiAlH4 and H2SO4 in Et2O at -80 °C, afford alane-rich hydride-bridged polymers exhibiting a range of bonding modes of Lewis bases to AlH3 including unprecedented mono Al···H hydride bridging.
