Synthesis, Crystal Structures, Magnetic Properties and Hirshfeld Surface Analysis of Cu/Mn Coordination Polymers

Abstract Two new coordination polymers [Cu( L )(phen)] n ( 1 ) and {[Mn 2 ( L ) 2 (phen) 2 ]⋅H 2 O} n ( 2 , H 2 L is 4,4′‐(azanediylbis(methylene))dibenzoic acid, phen is o ‐phenanthroline) were synthesized using hydrothermally method. Complexes 1 and 2 were characterized by powder XRD, FT‐IR, elemental analysis, thermogravimetry, and X‐ray single‐crystal diffraction. Complex 1 belongs to monoclinic system with space group P 2 1 / n while complex 2 belongs to triclinic system with space group P ī. Complex 1 is 1D coordination polymers while complex 2 is 2D coordination polymers. Hirshfeld surface analysis of 1 and 2 were investigated and discussed in detail. Moreover, Magnetic studies reveal that complex 2 displays dominant antiferromagnetic interactions between Mn II ions through syn‐syn ‐carboxyl bridges.
