A large negative magnetoresistance effect in semiconducting crystals composed of an octahedrally ligated phthalocyanine complex with high-spin manganese(iii).

ABSTRACT: A design for an octahedrally ligated phthalocyanine complex with high-spin manganese(iii) (S = 2) and Mn^III(Pc)Cl₂ (Pc = phthalocyanine) is presented. The presence of high-spin state Mn^III in the fabricated Ph₄P[Mn^III(Pc)Cl₂]₂ (Ph₄P = tetraphenylphosphonium) semiconducting molecular crystal is indicated by the Mn-Cl distance, which suggests an electronic configuration of (d _yz , d _zx )²(d _xy )¹(d _{z ²} )¹. This was confirmed by the Curie constant (C = 5.69 emu K mol^-1), which was found to be significantly larger than that of the isostructural Ph₄P[Mn^I
