text: In methyl thiocyanate,  and  distances are 116 and 176 pm. By contrast,  and  distances are 117 and 158 pm in isothiocyanate]s.  
  Typical bond angles for  are 100°. By contrast   in aryl isothiocyanates is 165°. Again, the thiocyanate isomers are quite different with  angle near 100°.
  In both organic thiocyanate and isothiocyanate isomers the  angle approaches 180°.
