{5,5'-Bis(diethyl-amino)-2,2'-[(2,2-dimethyl-propane-1,3-di-yl)bis-(nitrilo-methanylyl-idene)]diphenolato}dioxido-molybdenum(VI).

In the title compound, [Mo(C(27)H(38)N(4)O(2))O(2)], the Mo(VI) atom is coordinated by two oxide O atoms and by two O and two N atoms of the tetra-dentate Schiff base ligand in a distorted octa-hedral geometry. The Mo-N bond trans to a terminal oxide group is significantly longer than the other Mo-N bond, which is attributed to the strong trans effect of the oxide O atom. The dihedral angle formed between the substituted benzene rings is 71.79 (14)°. One of the ethyl groups is disordered over two sets of sites, with a refined site-occupancy ratio of 0.588 (18):0.412 (18).

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.
