Magnetic properties of potassium dichromate

Is $\ce{K\_2Cr\_2O\_7}$ diamagnetic or paramagnetic?  

While näive theory predicts it's diamagnetic, but we can't be sure.  

I cannot find any literature on this topic.  

Nor does Wiki has that information.  

Even Chem spider doesn't.  

I don't know about any other reliable sources.
