Abstract
Abstract In most intermetallic europium compounds, the Eu atoms exhibit a divalent oxidation state with a high effective magnetic moment since Eu2+ is isoelectronic with Gd3+. Trivalent intermetallic Eu compounds, in contrast, are extremely scarce and under 20 examples are known to literature. This mini-review summarizes the known binary and ternary examples along with their crystal-chemical peculiarities as well as their magnetic and 151Eu Mössbauer spectroscopic behavior. Additionally, compounds that exhibit valence phase transitions are summarized.
期刊介绍:
Reviews in Inorganic Chemistry (REVIC) is a quarterly, peer-reviewed journal that focuses on developments in inorganic chemistry. Technical reviews offer detailed synthesis protocols, reviews of methodology and descriptions of apparatus. Topics are treated from a synthetic, theoretical, or analytical perspective. The editors and the publisher are committed to high quality standards and rapid handling of the review and publication process. The journal publishes all aspects of solid-state, molecular and surface chemistry. Topics may be treated from a synthetic, theoretical, or analytical perspective. The editors and the publisher are commited to high quality standards and rapid handling of the review and publication process.
