Round 1

Reviewer 1 Report

This work is devoted to the synthesis and detailed investigation of two layered Cu(II) coordination polymers based on 4’-(3,5-dicarboxyphenyl)-2,2’:6’,2’’’-terpyridine (H2dtp), an almost unexplored ligand. Both compounds synthesized were structurally and spectrally characterized. Moreover, thermal properties were studied. In my opinion, the findings presented in the reviewed work are interesting for researchers dealing with MOF materials. Therefore, I recommend acceptance this paper after revision to address the following concerns. 
1. In the Introduction, I recommend to extent the references on the MOFs over the following works:  10.1039/D0DT01127D, 10.1021/acs.inorgchem.1c00480, 10.1021/acs.chemmater.0c03984, 10.1021/acs.inorgchem.8b03364, 10.1039/C5TC01273B.
2. In microanalysis of 1, the experimental content of the carbon significantly differs from the calculated one (57.20 versus 57.92). The same is true for the nitrogen percentage. Please check this issue. 
3. Although I am not a native speaker, I feel that English needs to be thoroughly tested and improved.

Reviewer 2 Report

MOFs (metallo-organic frameworks) are difficult to get structures from. In this lucky case, the unit cell appears to be small, the crystals are large and stable and the X-ray data quality is good. Thus, after inspecting table 1 I detect no further problems in the single crystal X-ray structures. The interpretation of the results is plausible. One issue concerns the powder X-ray diffraction data. I disagree with the assessment of the authors that the experimental data agrees well enough with the simulated data to proof phase purity and homogeneity. Why not skip the powder result all-together given the far more conclusive single crystal X-ray data?
