| Popis: | Chemical communications 54(92), 12934 - 12937 (2018). doi:10.1039/C8CC06741D The trinuclear copper(II) complex [Cu$_3$(saltag)(py)$_6$]ClO$_4$ (H$_5$saltag = tris(2-hydroxybenzylidene)triaminoguanidine) was synthesized and characterized by experimental as well as theoretical methods. This complex exhibits a strong antiferromagnetic coupling (J = −298 cm$^{−1}$) between the copper(II) ions, mediated by the N–N diazine bridges of the tritopic ligand, leading to a spin-frustrated system. This compound shows a T$_2$ coherence time of 340 ns in frozen pyridine solution, which extends to 591 ns by changing the solvent to pyridine-d$_5$. Hence, the presented compound is a promising candidate as a building block for molecular spintronics. Published by Royal Soc. of Chemistry, Cambridge |
