Low‐dimensional compounds containing cyano groups. X. (Dicyan­amido‐κN1)­bis(1,10‐phenanthroline‐κ2N,N′)copper(II) perchlorate

The title compound, Cu(C₂N₃)(C₁₂H₈N₂)₂]ClO₄, represents a relatively rare class of compounds with dicyan­amide coordinated in a monodentate manner. The structure is formed by the Cu{N(CN)₂}(phen)₂]⁺ complex cation (phen is 1,10‐phenanthroline) and an uncoordinated ClO₄^? anion. The Cu atom is five‐coordinate, with a slightly distorted trigonal–bipyramidal environment. The dicyan­amide ligand is coordinated through one nitrile N atom in the equatorial plane, at a distance of 2.033 (6) Å from the metal. The two axial Cu—N distances are similar mean 1.999 (4) Å] and are substantially shorter than the remaining two equatorial Cu—N bonds mean 2.087 (1) Å].
