title: Mixed-Valence Nickel Bis(azamacrocycle) Compounds with Ghost-Leg-type Sheets.
abstract: The fabrication of so-called ghost-leg sheets and their electronic properties is reported. This unique sheet structure is composed of one-dimensional mixed-valence nickel chains, which are linked with one another by bis(azamacrocycle) ligands. They are also topologically unique NiII/NiIIImixed-valence complexes, as confirmed by X-ray and optical measurements. Moreover, their magnetic susceptibilities indicated two-dimensional antiferromagnetic behavior following the Fisher 1D chain model with interchain interactions, where spins on NiIIIsites mutually interact antiferromagnetically in the sheets.
