Abstract:  The following new cyanatocopper(H) complexes with organic diamines were prepared and studied using infrared, electronic, and e.s.r. spectroscopy and magnetic susceptibility measurements at room temperature :**Cu(NCO)₂(o-phen)H₂0, Cu(NCO)₂(/m-, p-phen)0,5H₂O, Cu(NCO)₂(paz), and Cu(NCO)₂(o-tld)₂. Structures of the complexes Cu(NCO)₂(m-, p-phen)0.5H₂O and Cu(NCO)₂(paz) consist of infinite chains linked by bifunctional diamine ligands. There are some indications that Cu²⁺ ion interacts axially with cyanate groups. Structure of Cu(NCO)₂ (o-phen) . H₂0 exhibits some peculiarities, nevertheless the molecules of ö-phenylenediamine are also bifunctional. Cu(NCO)₂(o-tld)₂ possess a molecular structure with monofunctional o-tolidine molecules and a distorted tetrahedral arrangement of ligands.
