2‐Amino‐4‐(2‐pyridyl)thiazole (H 2 L) complexes of iron(III), iron(II), cobalt(II), nickel(II) and copper(II) have been prepared for the first time. The oxido‐bridged dinuclear ferric complex [(H 2 L) 2 FFe III (μ‐O)Fe III F(H 2 L) 2 ](BF 4 ) 2 ( 1 ) and the mononuclear difluorido complex [Fe III (H 2 L) 2 F 2 ](BF 4 ) ( 2 ) were prepared with Fe(BF 4 ) 2 · 6H 2 O. Complex 1 contains strong antiferromagnetically coupled iron(III) ions. In addition, the mononuclear 3:1‐type complex [Co(H 2 L) 3 ](ClO 4 ) 2 ( 3 ) and the mononuclear 2:1‐type complexes [Cu(H 2 L) 2 ](ClO 4 ) 2 ( 4 ) and [M(H 2 L) 2 (NCX) 2 ] ( 5 : M = Fe, X = S; 6 : M = Fe, X = Se; 7 : M = Co, X = S; 8 : M = Ni, X = S) were prepared.
