The molecular structures of blue dichloro‐tetrakis(acrylamide) cobalt(II), [Co{ O ‐OC(NH 2 )CH=CH 2 } 4 Cl 2 ] ( 1 ) and pink hexakis(acrylamide)cobalt(II) tetrachlorocobaltate(II), [Co{ O ‐OC‐(NH 2 )CH=CH 2 } 6 ][CoCl 4 ] ( 2 ), characterized by single X‐ray diffraction, IR spectroscopy and elemental analyses, are described. The coordination of Co II in 1 involves a tetragonally distorted octahedral structure with four O‐donor atoms of acrylamide in the equatorial positions and two chloride ions in the apical positions. The second complex 2 in ionic form contains Co II cations surrounded by an octahedral array of O‐coordinated acrylamide ligands, accompanied by a [CoCl 4 ] 2− anion.
