Abstract

|
|
|
A new series of dioxo-di-μ-oxo-dimolybdate(Ⅴ),(*image) has been prepared by the reaction of pyridinum oxoisothiocyanato-molybdate(Ⅴ) with 1, 6-diaminohexane-N, N, N', N'-tetraacetic acid derivatives containing amine carboxyl groups. The properties and possible molecular structure of these complexes were discussed by elemental analysis, spectroscopic studies and magnetic susceptibility measurements. The infrared spectra of these complexes show two strong Mo=Ot stretching modes in the 900∼965cm-1, MoO2Mo stretching bands at around 450∼500 and 740∼765 cm-1 to symmetrical and asymmetrical O-bridge stretching, a coordinated COO- asymmetrical band in the 1600∼1635 cm-1. The complexes synthesized were yellow or orange and diamagnetic.
