Synthesis and magnetic behavior of the tetrahedral cage complex [(cyclen)4V4(CN)6]6+.
Reaction of [(cyclen)V(CF(3)SO(3))(2)](CF(3)SO(3)) with 4 equiv. of Et(4)N(CN) in DMF generates the seven-coordinate complex [(cyclen)V(CN)(3)], while a reaction employing just 1.5 equiv. produces a tetrahedral cage complex, [(cyclen)(4)V(4)(CN)(6)](6+), in which antiferromagnetic coupling leads to an S= 0 ground state.
