Tris(2-acetylcyclopentan-1-onato-κ2 O,O′)aluminium
نویسنده
چکیده
In the title compound, [Al(C(7)H(9)O(2))(3)], the Al(III) cation is coordinated by six O atoms from three 2-acetyl-cyclo-penta-nonate ligands in a slightly distorted octa-hedral environment, with Al-O bond lengths in the range 1.882 (2)-1.896 (2) Å. In the crystal, mol-ecules are linked together via C-H⋯O inter-actions. One of the C atoms in one ring has a large thermal motion compared to the other atoms, indicating some possible disorder. However, the treatment of this C atom as disordered over two positions did not give a significant improvement.
