Hello, Wedad A. Alwesabi.

Let's interpret what your data shows. You get a single peak, and we can't see any other. Well, it's not possible that a material would exhibit only one peak in this range. The point is that the peaks are there, but they weren't detected. Why so?

You mentioned that you used solvothermal method to synthesize this MOF. It's known that this method favors the formation of nanoparticles, and we know from Scherrer equation that small crystallites result in broad shape peaks. And yes, this peaks is kind broad. Other consideration is the noise of background. Somehow, this data is very noise, which can contribute to hide small peaks. And probably there is preferential orientation in this sample. So, preferred orientation, broad peaks and intense noisy, are not what you want to identify your material

Take 1:1 ratio of yours precursor. If you could share the precursor that you are used it will be easy to tell what's the wrong with this plot. The XRD plot that you shared is not ZR-MOF.

Poomani Af, thank you, this plot after baseline, but the real plot is below
