Abstract

The crystal and molecular structure of (tBu)3AlP(nPr)3 has been determined. The Al(1)−P(1) bond distance [2.594(3) Å] is slightly longer than other aluminum-phosphine complexes; however, the geometry about aluminum is similar to that of the [AlCl(tBu)3]− anion, suggesting that the geometry about the aluminum in tri-tert-butylaluminum complexes is defined by the size of thetert-butyl ligands and not as a consequence of the steric bulk of the Lewis base. Crystal data: Monoclinic,P2t,a=8.932(2),b=16.832(3),c=9.328(2), Å, β=114.36(3)°,V=1277.6(6) Å3,Z=4,R.=0.055,R w =0.053.
