I am curious of the reason why the V=O stretching here has a lower frequency than that in VO(acac)2. Is it related to resonance? I am not sure.

I think there should be four bonds except the V=O ? also, one acac is substituted by piperidine, isn't it?
Hello there,warenzeichen said:about 40 cm^-1
the V=O stretching vibration for VO(acac)2 at 995cm^-1 and for VO(acac)-piperidine it is at 957cm^-1
I think there should be four bonds except the V=O ? also, one acac is substituted by piperidine, isn't it?
Thanks.
VO(acac)-piperidine is a chemical compound consisting of vanadium (VO), acetylacetone (acac), and piperidine. It is a coordination complex with a central vanadium atom bonded to two acetylacetone molecules and one piperidine molecule.
VO(acac)-piperidine is a greenish-yellow crystalline solid with a melting point of 180-190 degrees Celsius. It is soluble in organic solvents such as chloroform and acetone, but insoluble in water.
VO(acac)-piperidine can be synthesized through the reaction of vanadium(III) chloride with acetylacetone and piperidine in the presence of a base, such as triethylamine. The reaction proceeds through a series of steps involving the formation and rearrangement of intermediates.
VO(acac)-piperidine is commonly used as a catalyst in organic reactions, particularly in the oxidation of alcohols. It is also used in the synthesis of other coordination complexes and as a precursor for vanadium oxide nanoparticles.
VO(acac)-piperidine is considered to be of low toxicity, but it should still be handled with caution. It may cause skin and eye irritation, and ingestion may cause gastrointestinal irritation. Proper safety precautions should be taken when working with this compound.
