Reaction of CoCl 2 ·6H 2 O with equimolar bis(3,5‐dimethylpyrazolyl)methane (dmpzm) produced a mononuclear adduct [Co(dmpzm)Cl 2 ] ( 1 ). Treatment of 1 with sodium dicyanamide (dca) afforded a polymeric complex [Co(dmpzm)( μ ‐dca) 2 ] ∞ ( 2 ). 1 and 2 were characterized by elemental analysis, IR spectra, thermogravimetric analysis and single‐crystal X‐ray diffraction. The cobalt atom in 1 adopts a distorted tetrahedral coordination geometry, bound to two N atoms of one dmpzm and two Cl atoms. Complex 2 has a 2D brick‐wall network (extended along the bc plane) in which the {[Co(dmpzm)( μ ‐dca)] 2 } 2 n + n chains are interconnected by pairs of μ ‐dca anions along the c axis. The magnetic properties of 1 and 2 were also investigated.
