In the reaction of 1,3-dimethylpyrazole-5-carboxylic acid (HL) with M(OAc) 2 ·4H 2 O, (M = Cu or Co), two novel complexes were prepared, the square-planar [CuL 2 (H 2 O) 2 ] and the octahedral [CoL 2 (MeOH) 4 ]. The crystal structures were determined by single-crystal X-ray diffraction. In both complexes, the deprotonated acid displays monodentate coordination to the metal ions. According to the results of a CSD survey, this is the first structural report on the metal complexes with an N 1
