Magnetic canting or not? Two isomorphous 3D CoII and NiII coordination polymers with the rare non-interpenetrated (10,3)-d topological network, showing spin-canted antiferromagnetism only in the CoII system.

The in situ solvothermal reaction of 3,4-dicyano-1,2,5-thiadiazole with MCl2 (M = Co, Ni) and NaOH afforded two isomorphous complexes, [M2(L)2(H2O)2]n (L = 2,1,3-thiadiazole-4,5-dicarboxylate), which exhibit a rare non-interpenetrated (10,3)-d (utp) network topology and interesting magnetic behaviors: spin-canted antiferromagnetism for the CoII complex, but simple antiferromagnetic coupling for the NiII.
