Solution and Solid-State Spin-Crossover Behavior in a Pseudotetrahedral d^7 Ion

Abstract

This Communication describes a pseudotetrahedral d^(7) complex, [PhBP_(3)]Co(OSiPh_(3)), 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.
