[SmNi(pic)3(H2O)5]n(ClO4)2n · 3nH2O, the first Sm–Ni heterometallic complex of picolinic acid ligand showing novel basket weave topology: Synthesis, structure and magnetics

The first basket weave framework topology of Sm–Ni heterometallic complex with picolinic acid as bridging ligand showing two different coordination modes of picolinic acid has been characterized; The studies on temperature-dependent magnetization indicate the title complex follows the Curie–Wiess paramagnetic behavior down to 5 K.
