Summary New cyanato-copper(II) complexes with aminopyridines (ampy) were prepared and studied;viz. Cu(NCO)2(3-ampy)2 (α- and β-form), Cu(NCO)2(3-ampy)2(H2O), Cu(NCO)2(4ampy)2, and Cu(NCO)2(2-ampy). According to physical results, the Cu(NCO)2L2 complexes exhibitpseudo-octahedral structures with amine nitrogens or cyanate oxygens occupying axial sites. For α- and β-Cu(NCO)2(3-ampy)2 the crystal structure reorganization is connected with a change in axial distortion. The compound Cu(NCO)2(2-ampy) is square pyramidal or — more probably — rhombic octahedral and its strong antiferromagnetism reveals the N-bridging function of the NCO groups.
