摘要：

The molecular structure of Al((t)Bu)(3)(NH(2)CH(2)CH(2)Ph) is determined by the crystal packing of the phenyl rings and the pseudo spherical Al((t)Bu)(3) units, and may be viewed as a layered structure consisting of double sheets of the phenyl rings and the Al((t)Bu)(3) units. The Al-N-C-C linkage shows severe disorder as a result of its flexibility. The structure of Al((t)Bu)(3) (NH(2)CH(2)CH(2)Ph) 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) Angstrom, V = 4388(10) Angstrom(3), Z = 4, R = 0.0957, R(w) = 0.0957.
