Abstract
Treatment of [VCl3(thf)3](thf = tetrahydrofuran) with bpy (bpy = 2,2′-bipyridine) and NaO2CEt in a 1 : 1 : 3 molar ratio in Me2CO followed by addition of ClO4 – allows isolation of [V4O2(O2CEt)7(bpy)2](ClO4)[4(ClO4)], which contains a butterfly-like V4 unit; variable-temperature magnetic susceptibility studies show 1 to possess both ferro- and antiferro-magnetic exchange interactions leading to spin-frustration effects and an S= 3 ground state.Keywords
