Effects of Iodination on the Electrical Conductivity of Hydrogen Bis(Phthalocyaninato) Neodymium(III)

Abstract Partial oxidation of hydrogen bis(phthalocyaninato) neodymium(III) by molecular iodine dramatically increases electrical conductivity. The results are discussed in terms of structural models.

The Synthesis and Static Magnetic Properties of First-Row Transition-Metal Compounds with Chain Structures

The most authoritative reviews of exchange coupling in one-dimensional linear chain systems of transition-metal ions are now several years old.1–4 Recent advances are largely a result of systematic studies of magnetic properties in conjunction with structural determinations. Since a large number of systems have been investigated, we will discuss only one example of each type of behavior that has been found for each of the first-row transition-metal ions, and tabulate data for other systems which have figured prominently in the development of the field. For the most part, only those chain compounds for which rather complete structural and magnetic data are available will be considered here.

One-Dimensional Ferromagnetic Exchange Interactions and EPR Linewidth Anomaly in the Bis(μ-Aquo) Chain Of Hydrogen Copper(II) Maleate Tetrahydrate

Abstract Hydrogen copper(II) maleate tetrahydrate exhibits one-dimensional ferromagnetism with J = 0.6 cm−1. The EPR angular linewidth dependence shows a minimum along the chain axis, and has six minima/maxima points during a 180° rotation of the crystal about any axis normal to the chain axis.

Alternating Chain Magnetism in Catena-μ-Oxo-Hemiporphyrazinatoiron(IV), The First μ-Oxo Linear Chain Complex Of Iron

Abstract X-ray studies, Mossbauer, and magnetism show FeOHp to be an antiferromagneticaly coupled alternating chain with J = -133 cm−1, g = 2.3 and an alternation parameter of 0.4.
