Magnetic Diversity in Three-dimensional 2-Fold Interpenetrated Structure: Story of Two Compounds

Abstract

The magnetosturcutural correlation has been carried out of two newly synthesized 2-fold interpentrated three-dimensional structures. Compound 1, [Ni(L1)(L2)]. 2 DMF (where, L1 = BDC = 1,4-benzene-dicarboxylic acid, L2 = 4, 4-oxybis (N-(pyridine-4-yl) benzamide), DMF = N,N’=dimethylformamide) is a three-dimensional structure with 2-fold interpenetration. Compound 2, [Co(L3)(L2)]. 2 DMF (where, L3 = TDC = 2, 5-thiopehene-dicarboxylic acid) is also a three-dimensional structure with identical architecture like compound 1. Both the compounds were well characterised through several techniques like single crystal X-ray diffraction, powder X-ray diffraction, TGA, IR, etc. Magnetic and specific heat measurements revealed a canted-antiferromagnetic transition at TN ≈ 4 K and a field-induced spin-flop transition at a lower field for compound 1. These exotic features are attributed to the low-symmetry space group P (-1) and single ion anisotropy of the Ni2+ sub-lattice. On the other hand, compound 2 is found to be a weakly antiferromagnetic in nature with a negligible interaction between the magnetic Co2+ ions.
