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

Two new coordination polymers [Cu(L)(phen)]n (1) and {[Mn2(L)2(phen)2]⋅H2O}n (2, H2L 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 P21/n while complex 2 belongs to triclinic system with space group Pī. 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 MnII ions through syn‐syn‐carboxyl bridges. [ABSTRACT FROM AUTHOR]
