title: Solution and solid-state spin-crossover behavior in a pseudotetrahedral d7 ion.
abstract: This Communication describes a pseudotetrahedral d7 complex, [PhBP3]Co(OSiPh3), that exhibits thermally induced spin-crossover both in solution and in the solid state. Magnetic crossover behavior is achieved by confluence of the X-type ligand and the tripodal auxiliary employed. Four-coordinate platforms of the present geometry type may offer a new approach to magnetic spin-crossover behavior distinct from their electronically related pseudooctahedral counterparts.
