Cobalt(II) chloride complexes with 1,1'-dimethyl-4,4'-bi­pyrazole featuring first- and second-sphere coordination of the ligand

The first cobalt(II) complexes involving N,N'-disubstituted 4,4'-bi­pyrazole tectons reveal the relatively poor coordination ability of the ligand, resulting in a Co-pyrazole coordination ratio of only 1:2.
