Abstract New cyanato-copper(II) complexes of the type Cu(NCO)2 L 2 (L=2,3-, 2,5-, 3,4- or 3,5-lutidine, 3- or 4-ethylpyridine) and Cu(NCO)2 L (L=2,3- or 2,5-lutidine, 2-ethylpyridine) were prepared. Solid state electronic, ESR and IR spectral results show, that Cu(NCO)2 L 2 complexes have tetragonal structures varying from pseudooctahedral to practically planar forms, also involving a square-pyramidal arrangement. The β-form of Cu(NCO)2(2-picoline)2 was isolated and found to be a distortion isomer of the known α-form. According to physical results, Cu(NCO)2 L complexes exhibit highly distorted five-coordinate structures. Further knowledge about the influence of type, number and position ofL ligand alkyl groups on the structure-bonding properties of cyanato-copper(II) complexes was obtained.
