Synthesis and crystal structure of a triple-decker Cu<sup>II</sup><sub>3</sub>Tl<sup>I</sup><sub>2</sub> complex: first example of a thallium(I) system in the imino-phenolate Schiff base ligand family
<div><p>This report deals with the synthesis, characterization, and crystal structure of a heteropentanuclear Cu<sup>II</sup><sub>3</sub>Tl<sup>I</sup><sub>2</sub> compound [(Cu<sup>II</sup>L)<sub>3</sub>Tl<sup>I</sup><sub>2</sub>](NO<sub>3</sub>)<sub>2</sub> (<b>1</b>), where H<sub>2</sub>L=<i>N</i>,<i>N</i>′-ethylenebis(3-ethoxysalicylaldimine). This compound crystallizes in the monoclinic crystal system within space group <i>C2</i>/<i>c</i>. Each of the two symmetry related thallium(I) centers is located between a terminal and a common, central [Cu<sup>II</sup>L] by forming bonds with four phenoxo and three ethoxy oxygens. The three [Cu<sup>II</sup>L] moieties are parallel and hence <b>1</b> is a triple-decker system. Neighboring triple-decker moieties are interlinked by π⋯π stacking interaction and weak hydrogen bonds to generate 3-D self-assembly in <b>1</b>. Salient features in the composition and structure of the title compound are discussed; the title compound is the first example of a thallium(I) system in imino-phenolate Schiff base family.</p></div
