(Cyanato-κN){1-(E)-phen­yl(pyridin-2-yl-κN)methyl­idenesemicarbazidato-κ2N1O}copper(II)

摘要

The Cu^II atom in the title compound, [Cu(C13H11N4O)(NCO)], is N,N′,O-chelated by the mono-deprotonated Schiff base ligand and it is also covalently bonded to the nitro­gen end of the cyanate ion. The Cu^II atom shows a square-planar coordination that is distorted towards square-pyramidal owing to an inter­molecular Cu⋯Ncyanate inter­action [2.623 (2) Å], which gives a centrosymmetric dimer. In the square-planar description, the Cu^II atom is displaced out of the square plane [r.m.s. deviation = 0.048 Å] by 0.084 (1) Å in the direction of the apical occupant. In the crystal, adjacent complex dimers are linked by an amine N—H⋯N hydrogen-bond pair, also giving a centrosymmetric cyclic association [graph set R 2 ²(8)], generating a linear chain parallel to [110].
