New complexes of Mo(V) with Schiff Bases. Crystal structure of butylammonium di-mu-oxo-mu-acetato-bis[(N-butylsalicylideniminato-N, O)oxomolybdenum(V)] benzene, acetic acid solvate

The synthesis of Mo(V) Schiff base complexes derived from alkylamines and salycilaldehyde are reported. The compounds are characterised by chemical analysis, IR and UV/Vis spectroscopy. The title complex C4H9NH3[Mo2O4(N-C4H9-salim)2OCOCH3] • C6H6• CH3COOH is characterised by X-ray structure analysis. The structure is composed of a di-mu-oxo-mu-acetato-bis[(N-butylsalicylideniminato-N, O)oxomolybdenum(V)] anion, butylammonium cation and two solvent molecules: benzene and acetic acid. The Mo atoms of the dinuclear complex [with Mo-Mo bond of 2.5675(5) Å ; ; ] exhibit the octahedral geometry coordinated by a terminal Mo-Oterminal [<1.681(4)> Å ; ; ], a double Mo-Obridging [<1.940(3)>Å ; ; ], Mo-Oacetato with bridging function exhibiting a significant trans influence [2.325(3) and 2.353(3) Å ; ; ], Mo-Ophenolic [<2.050(3)> Å ; ; ] and azomethine nitrogen from a Schiff base [<2.192 (4)> Å ; ; ].
