Acrylamide complexes of metal nitrates: [M( O ‐OC(NH 2 )CHCH 2 ) n (H 2 O) m ][NO 3 ] 2 (M = Co( 1 ), Ni( 2 ) (n = 6 and m = 0) and Zn( 3 ) (n = 4 and m = 2)) have been determined by using single crystal X‐ray diffraction analysis. All complexes crystallize in the triclinic space group ${\rm P}{\bar 1}$ . The structures of 1 and 2 represent octahedral species [M(AAm) 6 ] 2+ (AAm = O ‐OC(NH 2 )CHCH 2 and M = Co or Ni) and uncoordinated nitrate ions. The structure of 3 involves the octahedral cation [Zn(AAm) 4 (H 2 O) 2 ] 2+ in which the Zn 2+ environment includes oxygen atoms of four acrylamide and two water molecules that are stabilized using ionic nitrate ions. The observations of the solid‐state IR spectroscopic vibrational frequencies of these acrylamide complexes are in agreement with the crystal structures.
