Is There Evidence for Non-Linear Thiocyanate or Selenocyanate Ions?

The structure of a mixed-valence copper complex with 1,10-phenanthroline, [Cu^II(phen)₂]–NC–[Cu^I(phen)((Se,S)CN)]- ­[(­Se,S)CN].0.5(C₂H₅OH), μ-cyano-1κN:2κC-(seleno,thio)­cyanato-2κN-tris(1,10-phenanthroline)-1κ⁴N,N′;2κ²N,N′-dicopper(I,II) (seleno,thio)cyanate semiethanolate, has been revised from space group Cc to C2/c. Refinement in C2/c has shown that, contrary to the Cc results, the (Se,S)CN anions can be described as approximately linear, as expected.
