ABSTRACT=<p>One Zn-Nd complex [Zn<sub>2</sub>Nd<sub>4</sub>L<sub>2</sub>(OAc)<sub>10</sub>(OH)<sub>2</sub>(CH<sub>3</sub>OH)<sub>2</sub>] (<bold>1</bold>) was synthesized from Schiff base ligand bis(3-methoxysalicylidene)ethylene-1,2-phenylenediamine (H<sub>2</sub>L). <bold>1</bold> shows nanoscale rectangular structure with sizes of about 0.8 × 1.1 × 2.8 nm. <bold>1</bold> exhibits typical near-infrared luminescence of Nd(III) under the excitation of UV-visible light. Further study shows that the complex displays luminescent response behavior to anions and nitro explosives, especially with high sensitivity to H<sub>2</sub><inline-formula><mml:math id="M1" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mrow><mml:mtext>PO</mml:mtext></mml:mrow><mml:mrow><mml:msup><mml:mrow><mml:mn>2</mml:mn></mml:mrow><mml:mrow><mml:mo>-</mml:mo></mml:mrow></mml:msup></mml:mrow></mml:msub></mml:math></inline-formula> and 2,4,6-trinitrophenol.</p>
