Abstract

Reaction of solid NH₄SCN with solid NaH and HMPA (1:1:2 molar ratios) in toluene produces two complexes, (NaNCS·HMPA)_n (1), which has an S···Na-linked polymeric structure (n = 2∞) with a repeat dimeric unit of form SCN·Na(μ₂-HMPA) ₂Na·NCS, and (NaNCS·2HMPA)_n (2), which is a discrete symmetrical dimer (n = 2) with two μ₂-HMPA ligands and with terminal HMPA and NCS^- ligands (one of each per Na centre) arranged trans; the reaction appears to proceed via an electrontransfer mechanism, radical species having been detected by ESR spectroscopy.
