In structures 1-3, the pca ligand chelates to the metal centers in a tris-chelating arrangement through proximal nitrogen and oxygen donor atoms. Structures 1-3 are monoclinic and crystallize in the space group C2/C. In structure 1, a=28.066(13)Å, b=8.036(4)Å, c=13.577(6)Å, and β=90.2(10)°. In structure 2 a=28.318(3)Å, b=8.089(4)Å, c=13.792(12)Å, and β=90.256(2)°. In structure 3, a=28.679(4)Å, b=8.051(13)Å, c=13.847(2)Å, and β=90.585(2)°. Graphical Abstract: Three new isostructural coordination complexes, M(pca)3, where M=Co, Cr, or Rh and 2-pyrazine-carboxylate (pca), have been synthesized solvothermally and characterized by single crystal X-ray diffraction and powder X-ray diffraction.
