| dc.description.abstractEn | Taking into account the general interest in photoswitchable nanomagnets, we present an original synthetic route to well-defined photoswitchable heterotrimetallic complexes. Our strategy demonstrates the feasibility of using a “molybdenum−copper” switchable complex with terminal cyanide ligands as relevant synthons for the rational design and synthesis of heterotrimetallic photoswitchable molecular architectures. Starting from a pentanuclear compound based on an octacyanometalated precursor, [Mo<sup>IV</sup>(CN)<sub>4</sub>(CNCu<sup>II</sup>(Me2en)<sub>2</sub>)<sub>4</sub>]<sup>4+</sup>, and a [Ni<sup>II</sup>(cyclam)]<sup>2+</sup> assembling building block, we succeeded in synthesizing a photoswitchable heterotrimetallic chain, denoted as {NiMo<sub>2</sub>Cu<sub>7</sub>}<sub><i>n</i></sub>. The compound has been characterized by single-crystal X-ray diffraction, UV−vis and IR spectroscopies, and powder magnetic and photomagnetic susceptibility measurements. Before irradiation, the compound behaves as a paramagnet with eight independent spin carriers (Cu<sup>II</sup> d<sup>9</sup>, <i>S</i> = <sup>1</sup>/<sub>2</sub>, and Ni<sup>II</sup> d<sup>8</sup>, <i>S</i> = 1). After irradiation, a long-lived metastable state persists until relatively high temperature (120 K) and is thermally reversible. | |
