dc.description.abstract <p>Single crystals of the new compound Tb<sub>3</sub>Zn<sub>3.6(1)</sub>Al<sub>7.4(1)</sub> were obtained from Al and Zn-rich ternary solutions. The title compound crystallizes in the orthorhombic La<sub>3</sub>Al<sub>11</sub> structure type (space group <em>Immm</em> (No. 71), <em>Z</em> = 2; <em>a</em> = 4.2334(1) Å, <em>b</em> = 9.9725(3) Å, <em>c</em> = 12.4659(1) Å). The inverse susceptibility above ca. 50 K shows Curie-Weiss behavior, and a metamagnetic transition is apparent in the <em>T</em> = 2 K field-dependent magnetization around <em>H<sub>c</sub></em> ∼ 20 kG. The resistivity increases with temperature in a roughly linear fashion, indicating the metallic character of this material. TB-LMTO-ASA electronic structure calculations indicate that this new intermetallic phase has all bonding states optimized in the [Zn<sub>4–x</sub>Al<sub>7+x</sub>] network, which classifies this compound among the so-called “polar intermetallics”. The calculations also provide a rationalization of the nonrandom ordering of Zn and Al atoms, which can be attributed to optimizing (Zn, Al)—(Zn, Al) orbital interactions.</p>
