Abstract
A unique chiral three-dimensional
magnet with an overall racemic double-interpenetrated (10,3)-a structure
of the formula [(<i>S</i>)-(1-PhEt)Me<sub>3</sub>N]<sub>4</sub>[Mn<sub>4</sub>Cu<sub>6</sub>(Et<sub>2</sub>pma)<sub>12</sub>](DMSO)<sub>3</sub>]·3DMSO·5H<sub>2</sub>O (<b>1</b>; Et<sub>2</sub>pma = <i>N</i>-2,6-diethylphenyloxamate)
has been synthesized by the self-assembly of a mononuclear copper(II)
complex acting as a metalloligand toward Mn<sup>II</sup> ions in the
presence of a chiral cationic auxiliary, constituting the first oxamato-based
chiral coordination polymer exhibiting long-range magnetic ordering
