(4,4',6,6'-Tetra-tert-butyl-2,2'-{[2-(di-methyl-amino)-ethyl]-nitrilo-bis-(methyl-ene)}diphenolato)dioxidomolyb-denum(VI) chloro-form monosolvate.

In the title compound, [Mo(C(34)H(54)N(2)O(2))O(2)]·CHCl(3), the molybdenum(VI) ion exhibits a cis-dioxide distorted octa-hedral geometry. Two anionic phenolate O-atom donors and two neutral N-atom donors of the ligand are trans and cis, respectively. The Mo=O bond lengths and the O=Mo=O bond angle are typical for six-coordinated dioxomolyb-denum(VI) complexes. The Mo-N bond lengths are longer than 2.30 Å, as expected for a trans O=Mo-N structure.
