چکیده
The asymmetric unit of the title compound, C(27)H(40)N(4)O(2), comprises one mol-ecule of a potentially tetra-dentate Schiff base ligand. The dihedral angle between the two phenyl rings is 67.13 (10)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. One terminal methyl among the four diethyl-amino groups is disordered over two positions with the refined site occupancy ratio of 0.660 (7)/0.340 (7).

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 for...
