Jf. Janik et al., LITHIUM PNICTIDOALUMINATES (ET2O)(2)LI[MU-E(SIME3)(2)](2)ALH2 (E = P,AS) - NEW MIXED-METAL PNICOGEN-BRIDGED 4-MEMBERED RING COMPOUNDS, Organometallics, 17(11), 1998, pp. 2361-2365
The lithium pnictidoaluminates (Et2O)(2)Li[mu-E(SiMe3)(2)](2)AlH2, E =
P (1) and As (2), were obtained from the reactions between LiAlH4 and
E(SiMe3)(3) in diethyl ether by following dehydrosilylation chemistry
described earlier by us for related gallium derivatives. No reaction
was detected for E = N. Single-crystal X-ray diffraction studies for 1
and 2 provided the isomorphous structural solutions featuring the pla
nar four-membered {Li[mu-E](2)Al} cores.
