Abstract

The molecular structure of Al(tBu)3(NH2CH2CH2Ph) is determined by the crystal packing of the phenyl rings and the pseudo spherical Al(tBu)3 units, and may be viewed as a layered structure consisting of double sheets of the phenyl rings and the Al(tBu)3 units. The Al−N−C−C linkage shows severe disorder as a result of its flexibility. The structure of Al(tBu)3 (NH2CH2CH2Ph) can be likened to a molecular “slinky”, in which the rigid ends are fixed in space by molecular packing forces, leaving the interior link to adopt multiple orientations. Crystal data: orthorhombic, Cmca,a=13.282(9),b=25.01(1),c=13.210(9), Å,V=4388(10) Å3,Z=4,R=0.0957,R w=0.0957.
