[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 Sm-Ni heterometallic complex with picolinic acid ligand has been synthesized, which displays the two-dimensional layered framework with the first reported basket weave topology; Studies on magnetic property indicate the existence of antiferromagnetic interactions for 1.
