N,N-Dimethyl­acetamide complex of aluminium(III) perchlorate

In the title compound, bis­[hexa­kis(N,N-dimethyl­acet­am­ide)aluminium(III)] bis­(N,N-dimethyl­acetamide)ium hepta­kis(perchlorate), [H(C₄H₉NO)₂][Al(C₄H₉NO)₆]₂(ClO₄)₇, the Al^III ion has an octa­hedral coordination environment. The singly charged cation lies on a centre of inversion. One of the anions lies on an inversion centre and is disordered; a second anion is also disordered. Three Al-O-C-N torsion angles deviate significantly from 180°, indicating that the Al-O bonds are displaced from the direction of the lone pair of the sp² O atom. This is ascribed to the steric hindrance of the ligand in an octa­hedral environment.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
